653 – Bookings with me, you, everybody

Posted on October 21, 2022 by ewand

Ideally, within an organization where people are expected to work together, they will use tools that have been around since the 1980s and actually share their calendar with their colleagues.

Outlook users can usually see blocks of when someone looks free or busy, when looking in the Scheduling Assistant tab on a meeting, though it won’t show external attendees and unless the attendees have chosen to share their calendar details, you won’t see anything other than tentative, free, busy or out of the office. Hopefully, some eejit won’t have blocked everyone else’s calendars by informing their colleagues of an impending day off.

When dealing with people in other time zones, there is a clue to whether they are likely to be able to join a meeting (quite apart from whether they have their calendar blocked or not) – the Work time setting is meant to show others what days and hours their expected work time is supposed to be.

Looking at the scheduling assistant grid, the light-grey area is supposed to be not-work time, and if there are any lighter-coloured blocks, that means they’re free and open for booking. Individually, you might also see their time zone displayed in their Profile Card when clicking on the user’s name in Outlook, Teams etc. Again, this is available for people in the same organization, so when dealing with external parties another approach will be required.

A variety of 3^rd party services exist to help people find time when others are free – a bit like a restaurant or hotel booking service, tools like Calendly or HubSpot (others are available) offer to expose your free time slots to selected external people, so they can find a slot that you are available and reserve it for a meeting with them. Office users could also use FindTime, which effectively sends a poll of suggested times to a group of people and gets them to vote on which one suits them best.

There’s also a Bookings application which is part of Microsoft 365; accessible via the app launcher icon (the grid of squares on the top left if you login on office.com using an account with an active M365 subscription). Bookings is designed to manage scheduling across a group of people – like in a hairdresser’s salon, where multiple members of staff could be available on different shift patterns, but a simple web UI is presented to an end customer so they can find a time when their favourite snipper is available.

Regular ToW contributor Ian Moulster spotted a new addition to Microsoft 365 which appeared in July, and though it may have common underpinnings, it’s a different offering to Bookings – called Bookings with me.

You might spot the Bookings with me notification in the top right of Outlook Web App, or try setting it up at outlook.office.com/bookwithme.

If available in your subscription, you can then set up a booking page with a menu of meeting types you want to accept – eg 20 minute 1:1 Teams calls in “public” (ie available to anyone who has your booking page URL – you might even add it to your email signature), or more specific meetings that are “private”, which you can choose to make available individually to sets of people. There are numerous of controls over how much time before and after the meeting, what days/times it can happen etc. Availability is synced with your Outlook calendar.

When you share the booking page or private URL with people, they just find themselves a time that’s free, and either sign in with a M365 work or school account or give another email address. If the latter, they will get an email with a verification code to enter into the booking form (M365 users are presumed already clean), and after confirming the code, they’ll get a meeting request sent from your calendar, with location and/or Teams details.

650 – All hands meetings

Posted on September 30, 2022 by ewand

Even though Dilbert isn’t funny any more there have been some good ones in the past, satirising corporate life. People who used to be cubicle or office based might struggle to deal with the new reality that most office workers would rather not be in the office 5-days-a week, 9 to 5, yet bosses would prefer people to not be slacking off at home in their PJs.

Zoom, Teams and other platforms adopted a metaphor in an online meeting, where attendees can figuritively raise their hand so they can be asked to speak. It works well when the people running the meeting have the discipline to check that they don’t have a forest of lifted paws before asking, “are there any questions?” to their audience.

It helps if presenters are not doing the lowest-common-denominator thing of sharing their desktop to present slides. Using Teams’ own slide sharing means you can see the chat, and who’s joined, and whether they have their hand raised.

Meeting participants also need to have the practice of raising their hand and waiting to be invited to talk, rather than blaring in to raise new topics or talk over others. Other attendees can also see who has their hand raised (look in the video gallery and you may notice those who have their hand raised are highlighted) and if you look in the People pane, you’ll see the order that attendees raised their hands as well, so if you’re the organizer then you can ask the top and most patient questioner to contribute at a point that makes sense.

A new etiquette has sprung up in hybrid meetings, though – how to balance commentary from remote attendees with chatter that’s happening in the room? Ordinarily, you’d rely on body language in a meeting room to decide it’s time to interject, nodding and perhaps making hand gestures yourself.

When some / half / most of the attendees are remote but you’re in the physical meeting room, it might be prudent to actually join the same Teams meeting on your PC – you’d only be sitting in the room looking at email on your screen anyway – and use the hand raise function before speaking, even if you’re sitting next to other contributors. This way, you’re on the same footing as all the remote attendees and it shows that you are at least giving the pretence of thinking about them too.

When joining a Teams meeting on your PC, there’s a yeah-yeah dialog box which pops up just before entering the “room”, which presents various potentially relevant audio related options. The norm would be to use comptuer audio, then select what speakers/mic you want to use.

These join options can also give you a number to dial in to (or be called by the meeting, so you can stay silent and camera-less on somebody else’s dollar).

If you’re the first to join while in a physical Teams Room, you could bring the room system into your meeting and control it from your machine.

If you are a bod in the room, though, then choose “Don’t use audio” to avoid any mic or speaker issues, causing endless echo. That way, you can enter the online meeting while being in the actual room, interact with other attendees on chat and use features like reactions and hand raising just as if you’re sitting at home.

Just remember that you are, actually, in front of other people, and also remember to change the default option back to “Computer audio” next time you enter a truly remote meeting, or you’ll spend the first few minutes saying “hello, hello? Can you hear me…?”

649 – Exploring SharePoint libraries

Posted on September 23, 2022 by ewand

SharePoint is now old enough that it could walk into a bar and buy itself a beer. It has changed a lot over the versions; starting out as a server product that would produce “portals” (or “digital dashboards”) it grew quickly to being rather more document-centric. SharePoint became the back-end for OneDrive for Business storage, and both have evolved a long way.

Two years ago, SharePoint was said to be used by over 200 million users. The following year, the Gartner MQ had it way out in front on the “Ability to Execute” Y-axis and slightly behind only one other supplier on the “Completeness of Vision” X-axis. It won’t be long now for the next MQ report to appear.

Nowadays, SharePoint underpins quite a lot of Microsoft 365 functionality, such as apps like Lists which provide a groovier UI over the top of the base web services, and the document oriented collab in Teams.

If you look at a file library in Teams, you’ll see a bunch of SharePoint-y options – you can Sync the content offline and it will be held offline, using OneDrive to sync it (and if you like, syncing only the files you’ve opened rather than the whole shebang).

The Sync’ed libraries show up in the Windows Explorer app, and in any number of applications’ File | Open / Save dialog boxes, so you can access and interact with the files through the apps you use rather than browsing to SharePoint.

You’ll see a collection of folders that have been set up to Sync, shown with your organization name, alongside any personal OneDrive and OneDrive for Business synced libraries.

The Download option (next to Sync on the Toolbar in Teams), creates a single ZIP file your computer, with the entire contents of the folder you’re looking at, so use it carefully.

One somewhat overlooked option further to the right of the toolbar (or may be on the ellipsis (“…”) menu): Add shortcut to OneDrive. This creates a shortcut link to the current SharePoint folder within your main OneDrive for Business storage, making it easy to find that SharePoint folder in the future, even though it’s not synced offline. The Add shortcut option is also visible on the ellipsis to the right of sub-folders when viewed in SharePoint or Teams.

Don’t add shortcuts to libraries – or sub-folders – which are already being Synced offline. That would be bad.

One downside to the OneDrive shortcut approach is that it just dumps the link into “My Files”, which is the root folder in OneDrive. The shortcut is named the same as the original source – so if you have lots of Teams folders with the same name (eg “Documents”), they will clash with each other as adding a new link would try to create a shortcut with the same name as one that exists already.

One solution would be to create a subfolder in OneDrive, called Sites (or similar), and after creating the shortcut to your latest Teams/SharePoint site, go to the root OneDrive folder and move your new shortcut – maybe renaming it too, so you can see what its parent site was (since the shortcut doesn’t make it clear what the source SharePoint site is) – you’d then have a Sites folder with lots of Shortcuts like Project Team – Documents etc.

Another side benefit of using shortcuts rather than Syncing offline, is that if you have multiple PCs – or feel like accessing OneDrive through a browser on a different machine altogether – you will always have access to the same collection of shortcuts, whereas the Sync offline capability is configured separately on each machine.

646 – Finding stuff in OneNote

Posted on September 2, 2022 (Updated September 1, 2022) by ewand

Many people ❤️ OneNote. It has evolved much over the ~20 years since it sprang from the “Scribbler” project at the turn of the century and was released in the Office 2003 wave, under the name which the developers disdainfully referred to as “Onay-no-tay”. A recent update to the OneNote strategy for Windows was covered in Tip #632.

There were other OneNote tips a few weeks previously, in Tip #617, including OneTastic, a great addin to the traditional desktop app – the ~~Metro~~ Modern app never had an addin capability.

As well as powerful macro capabilities, which can do things like generate tables of contents or sort pages and other works in ways that the base app doesn’t offer, the OneTastic addin includes the OneCalendar application – also available to install separately – which lets you see which OneNote pages were edited on each day.

If you keep a note of every meeting, stored in different places – by topic, by customer etc – then this is invaluable when it comes to finding notes, as you can see what you last wrote on a given day.

Of course, OneNote has searching capability where you could look across notebooks for key words. There is the ability to Tag notes too, and you can search across notebooks for tagged content.

A powerful yet somewhat hidden search capability in desktop OneNote is also available – you can press CTRL+F to search on a given page, or CTRL+E to run a simple query across multiple places, for where a particular word is mentioned.

Look, however, at the “Pin Search Results (Alt+O)” option at the bottom – it opens search results in a pane to the side, and lets you sort by different criteria, e.g. date modified.

This ALT+O option can only be invoked from within existing search results, so if you want to find all your recent notes with a searched-for word, press CTRL+E to start, then ALT+O and search by date modified to see the results clustered by month.

642 – Finding work stuff

Posted on August 5, 2022 (Updated August 5, 2022) by ewand

Data storage has become very cheap over the decades – a while ago, ComputerWorld wrote an article, saying that when it was founded 50 years previous, a 1MB hard disk would cost you $1M, and in 2017, that would work out at $0.02. 5 years later, $0.02 would get >1GB, more than 1,000 times as much.

This profusion has turned many of us into pilers – what’s the point of organizing data and deleting old stuff, be that files, emails, camera roll photos?

Outlook has a pretty good search function built in. OneDrive photos has some great organizing and filtering capabilities (like On This Day, or if you have GPS enabled on your camera/phone, you can easily group photos by the location taken from).

Still in OneDrive, there is also some AI-based tagging of your pics, which can sometimes be a bit hit & miss… but more often than not gets it about right.

While browsing “All Photos”, if you mouse-over to the right, you’ll get a scrollable timeline too (similar to the Windows Photos app), so you can quickly jump to a reference date.

Assuming you’re using Microsoft 365 / Office 365 at your workplace, there are other ways to find stuff that is more work-related, like documents, email and messages. One easily overlooked source is the “new tab” experience within the Edge browser.

The content on the default home page can be customized in a variety of ways, from choosing whether to show a background image or keep it clear; to displaying content from various “news” providers and clickbait advertisers that Microsoft News / MSN has elected to present to you, or hiding that altogether.

You can do some filtering of that content too, though for work purposes, many people may want to leave the page layout in “Focused”, which puts a link bar at the bottom and hides the content to be a scroll away.

Edge Profiling

If you have a “Work” profile (or you only have a single profile) and it is connected to your work account – ie your Microsoft 365/ Office 365 email address rather than your personal one – then you’ll see a “Microsoft 365” link within the list of content providers, which gives you a simple view of your most recent documents, SharePoint sites you visit and a whole lot more. To learn more about this Edge Enterprise tab, see here.

Also, you’ll see the search box containing your company name – it uses Bing to search for whatever you put in there (somewhat controversially, regardless of what your default search engine in the browser is…). Edge doesn’t give you the option – like IE used to – of starting a tab with a completely blank page, though there are hacks to make that work.

If you stick with the standard new tab, it will also give you the choice of restricting your search to “Work”, so looking at documents and the likes. You’ll see a list of content sources displayed on the left side as tabs, allowing you to filter what you’re looking for or where you want to search.

There’s a fairly new one that searches “Messages”. At least for now, that means Outlook and / or Teams messages, but it could be really useful when trying to remember if a conversation you had was in email or in a Teams chat.

A quick way to jump to this section is to go to aka.ms/messages

– regardless of which browser you’re using, as it uses the Bing.com/work back end.

640 – Smart Dates

Posted on July 22, 2022 by ewand

For all the time that computers have been used, date handling has been a problem. Bad dates cause problems from sorting lists to processing payments, yet many systems force the user to figure out what it expects by way of date entry – from web sites which force 2-digits (a la 01/01/22 vs 1/1/22) to non-localised apps which assume a date format without allowing it to be changed?

If you ever say a date out loud like “this report is due by eight-one”, meaning 8/1 or 1^st August, then 91% of the world’s population will need to interpret that differently to how they represent dates, since most will expect the format to be day-month-year, or arguably most sensibly, year-month-day.

Try saving things like expense reports or invoices using the file name starting yy-mm-dd or even yyyy-mm-dd and they’ll be much easier to handle (aside from just sorting by created date, of course).

When a user enters a date into a Windows app, the vast majority will respect the format set by the operating system, known as the User Locale.

That doesn’t help too much if the author of a spreadsheet – for example – is in one locale and other users are elsewhere; if the default date format is numeric, then the field remains in the format of the author, and that may cause befuddlement.

Switching display format to Long Date – or even setting a shorter custom format – could avoid confusion. Under the covers, Excel still stores the date in a universal format, but people might interpret it incorrectly when display in a different format.

Other tools can handle dates in surprisingly smart ways – even since its first version in 1997, Outlook lets you enter text into date windows like a Due Date for reminders or tasks – any time you are presented a date field that lets you type as well as select a date from a calendar picker, you can put stuff in like tomorrow, 2 weeks, next Friday, third Tuesday in October etc. There are shorter versions – 2w, 3m 10d – or you can string things together, like Monday before Christmas.

Microsoft To Do has also has some date smarts; if you type in a new task to track, it can read dates and times out of your task description and automatically set due dates and Reminders.

It has other kinds of parsing – in 3 days etc – though not quite as comprehensive as Outlook’s. There are also a load of special dates recognised (at least in the US).

So far, this functionality is available on Windows and iOS apps and for the most part it’s really neat. If it detects a date you don’t like – you’re suggesting something may happen, rather than it is happening on 1^st May, for example – then just hit backspace to clear that association.

#639 – Macros, Ghosts and GALs

Posted on July 15, 2022 by ewand

Since the early days, Microsoft always kept an eye on what its competitors were doing. It was once de rigeur to produce “battlecards” which would show feature-by-feature how one product is better than its competitor, thus assuring the customer they should buy this one. Thankfully, times have mostly moved on to just building as good a product as possible and then let customers and the markets decide – sometimes, they get improved and honed over time to be the best out there, and sometimes they get dispatched to the boneyard as times move on.

In the late 1990s, Office and Exchange (and later, SharePoint) Server were seen as Microsoft’s entrants into the burgeoning “Groupware” market, which became subsumed into “Knowledge Management” c2000. Key competitors to Exchange & Outlook were Lotus Notes and Novell GroupWise, both of which came from being collab tools and gained email functions. Notes was arguably much more mature and feature rich even if the UI was sometimes clunky, GroupWise was much leaner but found a niche in several industries. Amazingly, GroupWise is still a thing and Notes evolved first into IBM Notes/Domino and was eventually sold off to now be HCL Notes and HCL Domino.

One of the early moves Microsoft made to elevate Office apps to more than just writing documents, was to try to make the docs more capable through adding Macros, and later, Visual Basic for Applications. This allowed a moderately skilful user to dabble in programming to make smarter applications centered around documents; what seemed like a good idea at the time unwittingly unleashed a wave of malware, where bad actors wrote macros to do undesirable things. Following the “Melissa” worm in 1999, Office stopped Macros running without asking the user for permission. Using Macros for anything more than tinkering never really took off.

Macros disabled entirely

Microsoft announced in February 2022 that all Office Macros in content received online would be disabled completely; this was temporarily rolled back in some test builds for some changes to be made in how it works, but for many, the warning will still be there if you open a Macro-enabled file that you’ve downloaded or been sent.

There are still some very useful Office macros out there, and if you do need to run one that you know is from a trustworthy source, there is a workaround – save the file to your PC locally, then right-click on it to look at the file’s properties, tick the “Unblock” option and apply that. You’ll now be able to choose to run the macro unencumbered.

One such handy macro was discussed back in December 2021 in ToW 611, and is used to find Ghost meetings – ie ones you have arranged but everyone has declined (or at least not accepted). The macro spins through all future meetings in your calendar and lists the ones you’ve organised but where you’re likely to be the only attendee who shows up. Particularly useful at this time of year if lots of people are about to take time off over the summer, and may have declined a few recurring meetings but you – as organiser – still have them in your calendar.

For the latest version of the macro, download the ZIP file to your machine and expand it (or just copy the XLSM file that’s within and put it somewhere else), do the property Unblock thing as above, open in Excel, click the button to allow content, then the Scan Calendar button and you’re all set. You still need to go into Outlook and look at the appropriate date then decide if you want to cancel those meetings or not.

Another more powerful macro – though a little more esoteric – is one which does bulk resolution against the Global Address List, so if you give it a list of display names and/or alias names, it will show the full name, title, department, office, email, and alias name of that person. Handy if you want to get the full details of everyone who is going to attend a meeting, but if you just have a longish list of names then you could just paste them in and see how it goes. This was covered back in ToW 575. One usage scenario recently was to estimate the number of people who were attending a group meeting, but were based at other offices and would therefore need accommodation.

Here’s an example output of over 500 names who were invited to a large meeting; by just providing their display names in column A, it took the sheet about 30 seconds to complete, with 10 identified as distribution lists and 50 unknowns who couldn’t be resolved, either due to no longer being in the GAL or because there were more than one possible name listed.

If you can manually find the unknown person/people in the GAL, then get their alias name and paste that into column 1 instead of the ambiguous display name, then try to run it again.

635 – Outlook Wunderbar and Full Screen

Posted on June 17, 2022 by ewand

Many Office users rely so much on Outlook, it’s their most-used application by far. Over the years, numerous other apps – such as Yammer, Slack or Teams – have presented other ways to collaborate and communicate yet with billions of messages being sent every day, email just doesn’t seem to slow down.

The bones of the current Windows release of Outlook date back to Outlook 97, with some dialogs and settings having changed little since even if the main UI has been refreshed over the years. One recent change was the further evolution of Outlook 2003’s “Wunderbar”, the menu on the bottom left of the main Outlook window that switched views between mail, calendar, tasks etc (yes, it really was called that internally – look in the Registry).

By Outlook 2016, the navigation bar had collapsed into a series of icons along the bottom, which did the same thing but took up less screen real estate. It’s long been possible to use keyboard shortcuts to jump between the options on the navigation bar – CTRL+1 will go to the 1^st one (usually Mail), CTRL+2 to the second and so on. You can reorder the options on the bar if you like, so CTRL+1 could be Calendar if that’s what’s most important to you.

Outlook 2021 changes things again – the navigation bar has moved to the side, in a UI design shared with both Outlook.com and the Microsoft 365 Outlook Web App.

Other apps can be pinned to the new bar, too – including things like the Org Explorer, which presents a much more graphical way of looking at the org chart than the old Address Book in Outlook.

Moving these icons to the side of the screen might help organize screen real estate; another option would be to collapse the Ribbon, so you only see the many icons and options along the top of Outlook, when you need to use them.

You could try Simplified Ribbon to reduce the size and hide some of the more esoteric functions.

Show tabs only reverts to a simple menu bar, and when you click on one of the options, the ribbon for that tab is displayed. You can toggle easily between Tabs Only and the full ribbon by pressing CTRL+F1. There are loads of other shortcuts for Outlook though some are a little obscure.

To truly maximize your screen area, try going into Full-screen mode; that removes the menu and ribbon at the top of the screen entirely, including the search box.

If you need to search your mailbox while in full-screen, press ALT to temporarily display the ribbon, and look for the highlighted keys that can jump to specific tab or function.

Press Q, then type your search, hit enter and you’ll return to your results in full screen again.

631 – Why does nobody share calendars?

Posted on May 20, 2022 by ewand

Back in the late 1980s/early 90s, IBM had an internal email system called NOSS – an implementation of PROFS, a text-only mainframe-based system delivered via a terminal.

Even in 1990, NOSS allowed any user to browse a hierarchical directory (showing contact info, job titles, manager/reporting relationships etc), email or instant message anyone, and look at their calendar to see what they were doing. It was 10 years before you could do all those things using Microsoft Windows and Office. In recent years, Big Blue’s email environment has seemingly been less happy.

When Microsoft Exchange first came out, email was handled with the Exchange client and calendaring was from Schedule+, which had been updated to support Exchange (and lives on in some backward Microsoft lingo, where people who start every sentence with “So,” ask you to send them an S+, meaning, invite them to a meeting). Outlook came along in 1996 and became the preferred and unified way to do email, calendars, address books etc.

Some organisations had a default policy when new mailboxes were created that their calendar was shared Read-only, so anyone in the company could see it. You could open someone’s calendar fully in Outlook or by viewing the scheduling tab in a meeting, where you will typically see if a list of people are available or not. Others might have it that only free/busy info is visible by default, and that is pretty sub-optimal.

With M365 in general, newly-created mailboxes have no calendar sharing set up, and the action is on the user to choose how to let co-workers see their info.

Be a nice person, and check to make sure your colleagues can view your calendar.

Ideally, share so that others will see the title and location of any appointment; useful when someone is trying to arrange a meeting, as within the schedule view they can figure out if you are likely to be able to make the proposed meeting time – if your diary is full of blocks marked busy or tentative, they’ll have no idea if you really are in a meeting or have just marked time to do something that you might be happy to move. Or had a colleague’s FYI notice of being on holiday obliterate the view of your calendar.

In the early days of Exchange/Outlook, if you had read access to someone’s calendar, you could open up appointments, see who else was attending a meeting, download any attachments and so on, unless the appointment was marked “Private” – though it’s somewhat possible to open Private appointments programmatically if you know what you are doing.

Nowadays, calendar sharing is more granular – in Outlook Web App, go into Calendar and you’ll see the Sharing and permissions option, which will let you choose specific people and give them ability to see various details, or you can change the default for the whole organisation.

In full-fat desktop Outlook, click on the Share Calendar option on the ribbon, and you’ll get a 1990s-style dialog box allowing you to set the default permissions or to invite particular team-mates to have higher level access should you want them to know where you are and with whom.

If you choose titles & locations, viewers can’t open your appointments to peer inside, so can’t see who else is attending or what the body of the meeting says, but they can at least see if you’re likely to need travel time between meetings. See here for more info on calendar sharing & delegate access.

630 – slimming your PPT

Posted on May 13, 2022 by ewand

PowerPoint files can get big. In the scale of small vs large, sending a many-megabyte PPT file around between a few people might not matter much, but if you’re building a presentation that is going to be widely shared, it could cost actual money – data storage costs, bandwidth charges on a website, carbon footprint for transmitting and storing etc.

Estimates of the energy cost to transmit and store data vary wildly, but if 1 GB cost 1 kWh power and the average CO₂ output for generation was ~500g/kWh, then even shaving 10MB off a file can make a material difference if it’s going to be heavily used^†.

There are a few tricks you can follow to make your PPTs less massive – like compressing the images within, meaning that an embedded picture which was originally sized to print on a poster could be re-sized to fit on a screen.

If you see a few-slide presentation file and it’s dozens of MB in size, then there’s probably other info in the deck which is not necessary for your presentation. Even more likely is that there are some embedded graphic or video assets which are bloating the size of it. Quickly identifying the cause of such largesse might allow you to ditch the offending slide or resize/remove the content.

A somewhat cavalier way of looking for large things you can torch, is to make a copy of your PPTX file and then rename it so you can look within. The OfficeXML file formats (prevalent in Office 2007 and onwards) use the same compression as ZIP files, so if you rename your file as such, you’ll be able to open it in Windows Explorer or other ZIP handling utilities, to see its innards. Opening the file shows you a folder structure, and if you navigate into ppt \ media then sort by Size, you’ll quickly see what’s making your file so big.

Actually doing the rename might be trickier than you think, since Windows hides by default such grubby detail as file extensions. One trick is to flip the switch to show extensions again (in Windows Explorer, look under View menu / Show / File name extensions), then it’s a simple matter of changing the file in Explorer by editing the last part of its name from .pptx to .zip.

Once you’ve confirmed in the warning dialog that the apocalypse is nigh and you really do want to change file type, open the new ZIP file and you’re off. Remember to go back in and switch off the Show > File name extensions option if you’re so inclined.

If you’re still unsure about these new-fangled “gooey” interfaces, you could crack open the command line to do it quickly.

If all this grubbing about inside PowerPoint files makes you feel uneasy, there is one other trick that could yield dividends – look inside the Master. Since many people create a new presentation by starting with an old one, they liked, it’s very possible there are slide layout templates with embedded graphics that you no longer need – especially if the originating deck was produced for a conference.

Go into View menu and look under Slide Master, which will open a whole new tab specific to the management of these template slides that form the bones of the presentation. You may well see lots of title slides or similar, which have embedded background images – if you know you don’t need those graphics or those layouts, just delete them.

PowerPoint generally won’t let you ditch a master layout which is being used to format the current slide deck; so, if you have your deck already built and want to distribute it, just go into the Slide Master view, delete everything which looks unnecessary and that PowerPoint will allow you to, then Close the Master view to return to the main menu. Once you’ve checked that the presentation format hasn’t been garbled, go File > Save As and give it a new name. Now compare the size of the new and old files.

This title slide in the Slide Master view had a graphical background which was 17Mb in size; just deleting all the unnecessary visual slide templates dropped the size of the original file from 110MB to 26MB.

Running the Document Inspector to remove other content further dropped another 1.5MB.

Selecting an image from one of the 70-odd slides in the deck, and choosing Compress Pictures from the Picture Format tab reduced it again to only 11MB, or 10% of the original file size – all for a few minutes’ effort.

Going back to the original 110MB file and opening File > Save As, then choosing More options… will open a traditional Save As dialog box; on the bottom is a Tools > submenu which allows you to run the Compress Pictures function at the point of saving the file, so reducing it to 1/3 of the original size, for literally 15 seconds’ work.

†NB: the irony of sending a 2MB email to thousands of people, and sharing online and on LinkedIn, is not lost.
