One Drive for Business – what’s using my space?

One Drive for Business is a great feature included in your Microsoft 365 work subscription. There are however some pitfalls which occupy space that you may not be aware of.

The biggest of these is also one of the collaborative features – versioning of Office files.

When you create a file and store it on One Drive for Business you enable versioning by default. So you can update a file and it automatically creates a new version – you don’t need to save it as V1, V2, etc.

The changes are saved using a shredded saving method whereby changes are saved in small files, BUT as far as your quota and space use are concerned, Microsoft count every version as a full copy of the file.

So if you have a 10 MB Word file and have 100 versions of the file then you are deemed to be occupying approximately 1GB of space.

You may not need all those versions but all the time that you keep them they occupy space and that can mean you use up your One Drive space quite quickly.

The following shows you how to check your usage and how to remove unwanted versions of the file(s).


Checking your space.


Log into One Drive for Business and then from the Settings cog wheel (top right near your profile initials or photo) select One Drive Settings.

Accessing OneDrive for Business Site settings
Access OneDrive settings

Choose the More settings option and then look for the Storage Metrics option.

Accessing the settings
List of settings

Your One Drive contains other contents to make the system work, so you’ll need to select “Documents” which is the Documents library where your files are stored.

Viewing the storage metrics for the documents in your OneDrive
OneDrive documents

The Storage metrics view shows you the folders and files with the storage used, working from largest to smallest as you traverse down the list.

Viewing an unexpectedly large file

Where you see a large file, you can click on the Version History link to check for versions.

In the example below, my spreadsheet file has over 3,500 versions of a 1.7MB file.  With a default of 500 versions being stored, over 700 MB of space is being used.

Deleting all versions and the warning before completing this step
Using Delete All Versions and the warning message

You can click on the “Delete All Versions” link to remove all except the current version. The deleted versions are moved to the Recycle Bin and you have 90 days to recover these. You can choose to permanently delete these versions from the recycle bin but you should be aware that this is NOT reversible. Once removed from the Recycle Bin you cannot recover them.

Why so many versions?


The default number of versions for One Drive and SharePoint is 500. You can go into your One Drive settings and change the number of versions (N.B. the minimum number of versions that you can store is 100).

To change the number of versions follow the steps from the One Drive Settings menu – choose “Return to old Site settings Menu”

Then choose Site libraries and lists.

Accessing the site libraries and lists settings
Access site libraries and lists settings

Choose the Documents site library.

Choosing which library to customise
Choosing the document library to customise settings

Choose Versioning settings

Choosing the Versioning settings

Change the maximum number of versions and click OK.

Showing how to update the number of versions kept
Update the number of versions being kept

Note that the number you set has to be between 100 and 50000!

Error if incorrect number of versions chosen
Choose a valid number of versions to keep

Be very careful about increasing the number – you will potentially use up ever more space.

If you have files where the number of versions exceeds your current setting then when you next save a file with more versions, the system will automatically reduce the number of versions to the maximum number that you have set.

Outlook and Teams – New Meeting Response

Do you get invited to meetings which you can’t attend due to meeting clashes or a leave of absence, but where you want to know what happens and the decisions taken?


What is being introduced and When?

From late May 2024, Microsoft is introducing a new “Follow” response for meeting invitations.

Screenshot showing the "Follow" button as a valid response
Screenshot of the “Follow” button in a meeting invitation.

What happens?

Using the “Follow” button will let the meeting organiser know that you cannot attend the meeting but that you are interested in the details.

Screenshot showing Follow response in Organisers mailbox
Follow response returned to the meeting organiser

The organiser will be prompted about recording or transcribing the meeting. 

If this is done and the organiser has the Teams Premium license (Microsoft Teams Premium licenses – Office 365 News and Updates ( then a set of AI meeting notes will be delivered in the recap tab of the meeting making it easy for those who are following to catch up after the meeting happens.

M365 Updates for April and May 2024

A number of updates and changes have been published by Microsoft over the recent weeks. This blog post provides brief details about the ones that are most impactful for members of Imperial’s community.


Calendar Notifications in Teams Activity Feed

You can now get the Calendar Notifications in Teams from the Activity Feed. 

You will get calendar notifications in the Activity Feed for the following scenarios:

Meeting invite (including channel meetings you are explicitly invited to)
Meeting updates
Meeting cancellations
Meeting forwards (as an organizer)

When you get a calendar notification, you will see an unread notification in the Activity Feed pane or at the bell icon.

When you click on a notification, you will see the details of the meeting / event in the right pane.

Tags in Teams Private Channels

If you use tags within a team to associate groups of users, you can now use these tags for @ mentions inside Private channels.


Changes to the Website Tab in Teams

Microsoft Teams will be retiring the ability to load websites inside the new Teams client when using the Website tab. These website links will open in a new browser tab instead. This is to better align with emerging best practices in web security and privacy while also improving the reliability of websites opened through this feature.

Education tenants will be subject to this change but not before July 2024.

At the current time you are urged to plan for this forthcoming change which may not take effect until after summer 2024.


More videos visible in Teams meetings in Chrome and Edge

Microsoft Teams Meetings currently supports a maximum of 4 videos (2×2) on the screen by default (i.e., Gallery view) on web browsers.

With this update, users will be able to automatically see up to 9 videos (3×3) on Chrome and Edge on their screen by default without any additional explicit action.


Emojis, Gifs and Stickers in one unified “picker”

Users can soon find all of their emojis, GIFs, and stickers in a combined picker in Microsoft Teams.  This simplifies the experience and will be available by early May 2024 at the latest.


Hide the “general” channel in Teams

Similar to other channels in a team, now you will be able to hide general channels as well!  As a team member, when you become a part of a team, you see general channel always shown in your teams and channels list.  From April 2024 you will have the option to hide this channel from the list of channels that you see in your default Teams view.


Intelligent recap on iOS and Android

For users with a Teams Premium License ( Intelligent recap is now available in iOS and Android versions of Teams.  Meetings recorded or transcribed and where the organiser has a Teams Premium license will now be delivered with the AI generated meeting notes and actions in the same way as when recorded from a desktop device.


Planner App in Teams

The new Planner App is now available for use in Microsoft Teams.  Previously known as “Tasks by To-Do and Planner”, the new Planner App builds on the new releases of functionality in Planner and the new Planner Premium features.

Microsoft assure us that Planner Premium licenses will be available for Education tenants such as ours to purchase in due course.  If you wish to use Planner Premium features immediately then you should contact the Service Desk to purchase a Microsoft Project Plan 3 (Project Pro) license as this enables Planner Premium features today.

The new Planner was made generally available in mid April 2024 and more information about the released features and forthcoming features can be found at Microsoft’s announcement (The new Microsoft Planner begins roll out to General Availability – Page 2 – Microsoft Community Hub).  The new Planner is available within Imperial’s Microsoft 365 tenant.

Recordings and where they save on OneDrive

Teams meeting recordings will be saved into the Organiser’s OneDrive for Business instead of the person who initiated the recording. Microsoft is making this change for governance and compliance purposes and to ensure a simple and understandable policy for where the recording is stored.

The change will be made by the end of May 2024.  After that time all Teams meeting recordings will be stored in the OneDrive for Business of the account that organises the meeting.

Shorter Teams Meeting URLs

Microsoft are changing the format of the URLs for Teams meetings, removing some information and thus reducing the length of the URL.  This will make it easier to copy and paste meeting URLs into meetings or chats for quick access.

The change will be rolled out between mid May and late June 2024.

Teams for Web – Safari and Firefox

Up until April 2024 New Teams has only worked in the Chrome and Edge web browsers on Windows, macOS and Linux.  

With immediate effect, New Teams for Web on Firefox is available on Windows, macOS, and Linux. New Teams for Web on Safari is now available now on macOS


Media node in OneDrive for Business

Microsoft will be adding a Media node to the left navigation bar of Microsoft OneDrive for web that will allow customers to easily find all the photo and video content stored in their OneDrive in a single view.

When an end user navigates to the Media node, they will see a view of all the photo and video content stored within their OneDrive. 

This content will be sorted by the date the content was created.  The files shown in this view are the same files stored in the user’s OneDrive and the Media node does not create separate copies of the content.

End users will be able to perform actions on the media content in this view such as Share, Download, or Delete. These actions will behave the same way in the Media node as they do in the My Files node.

Screenshot showing the new media node in OneDrive
Media node in OneDrive

This feature should be visible by mid May 2024.


Loop components in OneNote

You can create or insert Loop components into your Microsoft OneNote notebook.

With Loop components in OneNote, users can:

  • Enhance Collaboration
  • Bringing unstructured, collaborative content from Loop components in Microsoft Teams and Microsoft Outlook into OneNote notebooks, fostering real-time collaboration and sharing.
  • Improve Productivity: Quickly augment and recall collaborative notes within the familiar workflow of OneNote, enabling tasks to be completed more efficiently.

Additional information:

You can find out more about Loop at Microsoft’s Loop introduction pages (Get started with Microsoft Loop – Microsoft Support)


Whiteboard – using @mentions in comments

When using Microsoft Whiteboard, users will be able to @mention other users within their tenant inside of a comment.

The flow will look and feel similar to other Microsoft Office applications such as Word, Excel, and PowerPoint.

The user will type an @ symbol followed by the name of the user they would like to @mention in the text of a comment.

If the @mentioned user is not actively using Whiteboard then they will be sent a notification via email and via the Microsoft Outlook notification bell.  Inside of Whiteboard, the @mentioned user will see a blue @mention badge on the comment in which they are mentioned.

Additional things to note:

Users will be shown a teaching callout within Whiteboard to inform them of the new @mention feature.
Similar to the blue @mention badge, users will see a new red badge on comments that will display the number of replies in that comment thread that they have yet to read.

This feature is planned to be available by late May 2024.

Microsoft Teams Premium licenses

The availability of third-party tools for Meeting AI capabilities, such as Meeting Notes, Actions, etc., has been rapidly rising.

Unfortunately, these AI systems are beyond Imperial’s reach or trust at the present time – see Imperial’s AI and Education Guidance Hub pages (  Additionally, licensing such capabilities is expensive and may expose college data to use in the training of future AI models such as ChatGPT, etc.

Staff who wish to use meeting AI can now request a Teams Premium license through ICT.

The Teams Premium license costs £20 + VAT per user per year (or part thereof).

What’s in the Teams Premium license?

Teams Premium licenses deliver intelligent meeting recaps, live translations, and advanced event capabilities.

Meeting AI—If you record or transcribe a meeting, the AI will generate a meeting summary and a list of actions recorded during the meeting.

Live Caption translation—A Teams Premium license allows meeting attendees to choose the language into which the captions they view are translated. There is a list of 40 current languages, with more being added constantly.

Advanced Event experiences—If you are a webinar or Town Hall user, the Teams Premium license will add additional functionality to these event offerings.

You can find out more about these features at Microsoft’s Learn site for Teams Premium (

How do I request a Teams Premium License?

You can order Teams Premium licenses by completing the request form at

Once checked, the cost will be charged to your nominated cost code, and the license will be provisioned against your account.

N.B. Teams Premium can only be provided for users with an A3 or A5 license – please validate your license eligibility by going to the photo profile or initials in your Office 365 pages (, then clicking on view account and choosing the subscriptions element. When viewing your subscriptions, you must check that you have either “Microsoft 365 A5 for faculty” or “Microsoft 365 A3 for faculty” applied to your account.

M365 Updates for March ’24 and beyond!

Microsoft have recently announced a slew of updates and feature changes for Microsoft 365 and Teams.  We’ve distilled down these changes to give you a quick summary of the updates that you’ll be seeing over the coming weeks.


Using your personal account in New Teams


Starting in April 2024 and rolling out gradually, the new Microsoft Teams desktop app on Windows and Mac will let you use any type of Teams account (work, school, or personal).


Meeting Recap


Launching in April 2024, shortly after a meeting ends, a recap message will appear in the meeting chat with links to the meeting recap page and meeting artifacts such as the transcript, the recording, any files shared in the meeting, and the meeting Collaborative notes and Whiteboard (if used).


New Planner App in Teams


The old Tasks by Planner and To Do app within Teams is being replaced during late March and early April. The new app will be called Planner and will bring together tasks from To Do (your personal productivity list), Planner (your groups tasks) and Project (if you have Project), allowing you to see all your work and personal tasks in one space.


Teams Calendar Meeting Notifications


By the end of April 2024, when you receive an invitation or an update to a meeting, a notification will be added tot he notifications area in teams giving real time notifications of new meetings, updates and changes.

If you schedule a new meeting in a Teams channel, then you can now choose to alert all the members and add it to their calendar. This should mean that team members no longer miss out on channel scheduled meetings.


Teams Meetings in Google Chrome and Microsoft Edge


If you are using a web browser to join a meeting then from the beginning of March you will be able to view an enhanced gallery of up to 9 videos on the screen instead of the previous 4. You need take no action to see this updated view.


Viva Engage – Create or Reply to a Post using email


The ability to create a new post or reply to an existing post directly using email will be retired from Viva Engage starting on March 31st, 2024.


To Do App on iOS


If you use the To Do app on an iPhone or iPad device, the new version has a minimum iOS version requirement of iOS 15.

Minimum versions for iOS and Android OS ensure security and bug fixes are optimised.


Retirement of MS Publisher – October 2026


In October 2026, Microsoft Publisher will reach its end of life. After that time, it will no longer be included in Microsoft 365 and existing on-premises suites will no longer be supported. Until then, support for Publisher will continue and users can expect the same experience as today.


New App Launcher in Microsoft 365


The new App Launcher experience will be rolling out between April and June 2024.

The new launcher should bring improvements in access to apps and ease of access to recent files too.

Picture showing the changes from the old launcher to the new launcher in Microsoft 365
Old vs New launcher


Retirement of Teams Live Events

In September 2024 Microsoft will turn off Live Events in Microsoft Teams. This will affect any users who have had access to Public facing Live Events.

What Now?

A new feature, called Microsoft Town Halls is being rolled out with greater capabilities than Live Events.

Town Halls feature a “green room” for pre-event preparation and bringing speakers together.

Town Halls also offer the ability to bring multiple speakers into view along with content such as presentations of screen shares or for panel style sessions with multiple speakers (up to 7 in view at any one time) – something that was difficult with Live Events.

Town Halls also offer the ability to send integrated emails for attendees – so no copying and pasting the attendee link into a separate calendar invitation in the future. Emails may also be customised further when the organiser has a Teams Premium license.

Live Events switch-off

Live Events capability will be switched off on the 31 July 2024. Staff who have Public Facing Live Event capabilities will be contacted in the coming weeks to discuss current and anticipated requirements going forwards.

New Town Hall users

ICT will shortly publish a new request form for Town Hall capabilities. Staff who wish to use Town Hall features will need to apply for this capability at least one month in advance of their planned event to ensure time for the College events team to review the request and for capabilities to be enabled, rehearsals held, etc.

Updating to the New Teams Application

What’s Happening?

In summer 2023, Microsoft made the new Teams application available for Windows and then Mac OS X systems in preview. As a result of the extensive use and testing and in order to move forwards with new features, Microsoft will be ending the Classic Teams application on Windows and Mac OS from 31 March 2024.

In advance of this enforced change, ICT will be updating the policy for all College users to use the New Teams application.

This change is planned for 27 February 2024 and will install the new Teams application at the next initiation of the application if you haven’t already switched over manually by 27 Feb.

Why the New Teams Application?

The classic Teams application has been in use for almost 6 years and can hog memory and processor resources making it unreliable on lower specification devices. Since the first iteration many new features have been added creating divisions in the application and it’s effectiveness.

The new version consolidates the changes into an improved application which uses much less computer resources, resulting in greater availability for other applications. Improvements in the underlying code also mean that the New Teams app is faster and more responsive.

What About Known Issues?

Microsoft maintain a list of known features for the New Teams application at

The main one that may affect a small number of users is the ability to produce Live Events in the New Teams application. An update is being released to allow this and will be available at the point when we change, or shortly after. For anyone who needs to produce a live event you will be able to switch back tot he old version of Teams to produce your event. Note that presenters will be able to use the New Teams application in a Live Event.

Microsoft 365 Feature Updates

The following are updates of particular interest or use for staff and students within College. Many have been demonstrated or discussed at the regular Microsoft 365 Ask Me Anything sessions (find out more at Ask Me Anything Sessions for the 2023 / 24 Academic Year – Office 365 News and Updates (

Microsoft Teams Updates

Private Channels – Tags and Channel Links

Private channels will support the use of tags that are generally available in MS Teams. You can use Tags for grouping people with similar responsibilities, grouping students into learning sets or dividing a large team into smaller sub teams for notifications, etc.

By the end of March 2024 you will also be able to create a link to the private channel(s) in your team. You can then use the link to direct people to the correct channel – as long as they are a member or owner in the private channel concerned.

Archiving of Team Channels

From end of February, Channel owners and teams admins will be able to archive a channel in a Team, making it read only for all. This will help people with using only the active channels while leaving information in the archived channels for cross-reference purposes.

Website tab in Teams

From April 2024, the website tab will cease to function. This change is being deployed by Microsoft to ensure security and privacy while improving the reliability of access to websites.

You will only be able to choose to open the website from the tab once the change has been applied.

Unification of Emojis, GIFs and Stickers in one picker

From the end of March 2024 you’ll find a single “picker” to choose emojis, GIFs and stickers. This simplifies the experience for all users and should be easier to use going forwards.

New Gallery view in Meetings

From March 2024 you will find a new Gallery experience and will be able to choose from 4, 9, 16 or 49 attendees per page.

At the same time both video and audio only meeting attendees will appear in a single sized window for easier identification of who is speaking and for spotlighting, etc.

Hide General Channel in Teams

From late March 2024 users will be able to hide the General channel in teams.

The General channel is always created when a new team is provisioned and by default is always visible for users added to the team.

Now users will be able to turn off / hide the General channel to allow focus on specific channels in the Team.

Team owners (admins) can always set the General channel to only allow owners to post in the General channel thus giving a clear admin announcements channel that doesn’t get cluttered with messages and chats that should be in appropriate channels.

Recap Tab

The Recording and Transcription tab for meetings will be replaced with a tab titled Recap.

The recap tab will contain the meeting recording with “in live viewing possible” along with a copy of the transcript.

Users with Teams Premium licenses will also find the AI generated meeting notes and actions in the Recap tab.

FindTime is Dead. Long Live Scheduling Poll


Microsoft are ending FindTime, the add-in for Outlook that allowed you to offer options for a meeting and have attendees vote for their preferred meeting option(s).


With effect from 11 December 2023 you will no longer be able to create meeting polls using FindTime.

What do I do now?

Instead of FindTime you should use Scheduling Poll which is the new option for meeting polls.

Scheduling Poll is built into Outlook for the Web and Outlook for Mac. It is also available for Outlook for Windows, but may not immediately appear depending on the update channel to which you are subscribed. Monthly update channels will see Scheduling Poll with immediate effect. Semi-Annual Enterprise Update channel users may not see Scheduling Poll until after January 2024.

If you need to use Scheduling Poll but don’t see it in your Outlook for Windows then head to your Outlook on the web and create your scheduling poll there.

Note: The create of polls is deprecated in FindTime but the visibility of polls remains available at

Additional Support

Microsoft Copilot with Commercial Data Protection (formerly Bing Chat Enterprise)

What is Microsoft Copilot with Commercial Data Protection (formerly Bing Chat Enterprise) ?

Microsoft Copilot with Commercial Data Protection (MS Copilot)  uses the Chat GPT 4 AI model to interrogate and deliver search results based on access to the data that you have.  Your data is protected and the chat results are NOT saved or made available for Microsoft, so the data does not pass outside of the organisation.


MS Copilot is grounded in data from the public web and provides complete, verifiable answers with citations, along with visual answers that include graphs and charts.


MS Copilot is designed by Microsoft in line with Microsoft’s AI Principles.


MS Copilot has no access to organizational data in the Microsoft 365 Graph.


How do I use MS Copilot?

Head to and sign in with your College ID (  NOTE Only Staff with an A3 or A5 license for Microsoft 365 services can access Bing Chat Enterprise at the present time.


Once signed in you will see a “Protected” flag beside your name indicating that you are using the secure version of Microsoft Copilot with Commercial Data Protection.


The font page will appear with options to select a particular style of conversation (Creative, Balanced or Precise).  

Image of Bing Chat Enterprise home page
Bing Chat Enterprise homepage

You can provide simple questions or more complicated multiple point paragraphs.  MS Copilot will then interpret your request and deliver results which you can then refine as needed.


MS Copilot also incorporates DALL-E for image creation – this can take a little while to respond depending on how complicated your request is.  You should also be careful to ensure that any image that you create correctly attributes any copyright for partial use from other published images.  Failure to do so may result in image copyright infringement and subsequent demands for payments or charges being levied through legal action.  If in doubt then adopt the premise of “don’t publish”!


Five Things to Try to Get Started

  1. Summarise a long document or article.
    Navigate to a long article or document (PDF) on the internet, then use the Chat sidebar in Microsoft Edge to ask MS Copilot to summarise the document in 5 bullet points.

  2. Draft emails and content that’s ready to send.
    Navigate to your Outlook on the web ( then use the Copilot icon in Microsoft Edge to ask MS Copilot to draft an email, e.g. “Draft an email alumni students asking them to consider leaving Imperial a gift in their will”.

  3. Create an image.
    In MS Copilot ask “Create an illustration of a shark jumping out of a coffee mug”.
    Try changing the shark to a dolphin.

  4. Learn new and useful information easily.
    In MS Copilot ask “Explain how large language models work  in simple terms”.

  5. Get answers to complex and specific questions.
    Try “Give me a table that compares Imperial’s undergraduate Medicine course to that of UCL”
