If your business uses Microsoft Whiteboard, you may have seen headlines suggesting the app is being shut down. A few important deadlines are landing in August and September 2026, and some of the coverage has made this sound more dramatic than it needs to be. Here is what is actually changing, and what your business should check before the dates arrive.
Is Microsoft Whiteboard being discontinued?
Short answer: not completely, if you're a Microsoft 365 business user. Microsoft is completing a long-running move away from an older, Azure-backed storage system for Whiteboard content, replacing it with the current OneDrive-backed version. At the same time, the standalone Whiteboard app for desktop and mobile is being retired.
To make sense of the changes, it helps to separate four things that often get blurred together:
- Legacy Azure-backed boards – older Whiteboards, typically created before 2022, that have not yet moved to the current storage system.
- Current OneDrive-backed Whiteboards – the modern format most boards created in recent years already use.
- The standalone Whiteboard app – the separate Windows and mobile application, rather than Whiteboard inside another Microsoft product.
- Whiteboard accessed through Teams and Microsoft 365 – the way most business users will continue to reach Whiteboard going forward.
It's really only the first and third of these that are going away. If your organisation is managed through Microsoft 365 Business Premium, Whiteboard itself is not disappearing.
What happens on 22 August 2026?
This is the date Microsoft's migration tooling for legacy commercial Whiteboards is switched off. Up to this point, opening an older Whiteboard on an eligible desktop client can trigger it to move automatically into the current OneDrive-backed format. After 22 August, that automatic route disappears, and any boards still sitting in the old system can no longer be migrated.
This is the point at which it's worth checking whether any important legacy boards in your business are still unmigrated, rather than assuming they've already moved across.
What happens on 5 September 2026?
Any legacy Whiteboards that haven't been migrated or exported by this date are scheduled for permanent deletion. Microsoft has been clear that there's no recovery option once this happens, and no way to migrate the content afterwards.
This is the deadline that matters most if your team has used Whiteboard for brainstorming sessions, project planning, workshop notes or client meetings over the years. If any of that content still lives in an older, unmigrated board, it's worth preserving before this date.
What happens on 14 September 2026?
The standalone Microsoft Whiteboard app for desktop and mobile is being deprecated and will no longer be supported. This doesn't mean Whiteboard disappears for Microsoft 365 business users – it means you'll be expected to access it through Microsoft Teams or the web instead of the separate app.
How do I know whether my Whiteboards are affected?
Boards you've created more recently are likely already stored in the current Microsoft 365 model and won't be affected. The boards worth checking are older ones, particularly any that haven't been opened for a while, since Whiteboard only starts the migration process when a user actively opens an affected board.
Working out exactly which boards in your organisation are still on the legacy system usually needs a look at the admin side of your Microsoft 365 environment. Rather than turning this into a technical exercise yourself, it's generally quicker to ask whoever manages your Microsoft 365 environment to check migration status on your behalf.
What should businesses do before the deadlines?
- Identify any Whiteboards your team considers important – project plans, workshop notes, sales or operations boards.
- Check whether older boards have already migrated to the current format, rather than assuming they have.
- Export or preserve any business-critical content held in boards that haven't migrated.
- Let staff know the standalone Whiteboard app is being retired, so they aren't caught out when it stops working.
- Pay particular attention to boards used by project, sales, operations or management teams, since these are often the ones with genuinely useful content.
- If you're not sure whether your boards are affected, contact whoever manages your Microsoft 365 environment.
Will Whiteboard still work in Microsoft Teams?
Yes. Once the standalone app is retired, Whiteboard continues to be available through Microsoft Teams meetings and the Teams tab, as well as through the web. For most business users, day-to-day use of Whiteboard inside Teams meetings isn't changing at all – it's really only people who relied on the separate desktop or mobile app who will notice a difference.
What about personal Microsoft accounts?
It's worth flagging a separate issue that's been mixed into some of the coverage: people using Whiteboard with a personal Microsoft account (rather than a work account) are losing the ability to create or edit boards from 22 August, with content deleted from 5 September unless exported first. That's a different situation from Microsoft 365 business accounts, which retain full access to Whiteboard. If you've seen alarming headlines about Whiteboard "shutting down", they are often talking about this personal-account change rather than the business service.
What should KES customers do?
If KES manages your Microsoft 365 environment, we can check whether your organisation has any legacy Whiteboards that haven't migrated, and help you preserve anything worth keeping before the September deadlines. Get in touch if you're unsure, or if you'd like a wider check of your Microsoft 365 environment while we're looking into it.
None of this needs to be stressful. The changes are really about tidying up an older storage system rather than removing Whiteboard from Microsoft 365 business users – but it's worth taking ten minutes to check your boards before the deadlines pass.
