Published: 17 August 2026. Updated: 16 October 2026. Microsoft permanently deletes unmigrated legacy whiteboards on 16 October 2026. The migration tool for legacy enterprise whiteboards retired on 25 September, so anything not already moved to OneDrive or exported by now cannot be saved. Microsoft announced the retirement in Message Center notification MC1441775 on 28 July 2026 and revised its timeline on 25 August.

What is changing and who is affected
Microsoft is retiring legacy whiteboards in favour of OneDrive-backed whiteboards, the format Whiteboard has used since Teams began storing whiteboards in OneDrive. Any legacy whiteboard that was migrated to OneDrive is safe. Any that was not migrated, and that its owner did not export, is deleted on 16 October 2026.
If your organisation uses Whiteboard through Teams meetings or the current web experience, those boards are already OneDrive-backed and are not affected. The boards at risk are older ones that never made the move.
Personal Microsoft account users are affected too. They lost the ability to create or edit whiteboards on 25 September 2026, and Microsoft told them to export anything they want to keep before 16 October.
The standalone Whiteboard apps are going as well. MC1441775 gives 30 November 2026 for the standalone desktop and mobile app; the later MC1469557 retires the Windows, iOS and Android apps on 16 October 2026 and says they will no longer give access to existing content after that date. Either way, Whiteboard continues in Microsoft Teams and the supported web experience.
For context on the earlier storage migration that moved Teams channel whiteboard files into SharePoint, see the related alert on Teams Whiteboard files moving to SharePoint channel sites. That change was about storage location; this retirement is about content that was never migrated at all.
The retirement timeline
| Date | Milestone | Impact |
|---|---|---|
| 25 September 2026 | Migration tool retired; personal accounts lose create and edit | Remaining legacy enterprise whiteboards can no longer be migrated to OneDrive. Personal Microsoft account users can no longer create or edit whiteboards. |
| 16 October 2026 | Unmigrated legacy whiteboards permanently deleted; standalone Windows, iOS and Android apps retired (MC1469557) | Any legacy whiteboard that was neither migrated nor exported is deleted and cannot be recovered. |
| 30 November 2026 | Standalone Whiteboard app deprecated (MC1441775) | The standalone app is no longer supported. Enterprise users use Whiteboard in Microsoft Teams. |
What admins should do now
With the migration tool gone and deletion on 16 October, there is little left to rescue. What remains is confirming what survived and cleaning up after the change.
- Verify the migrated whiteboards. Microsoft's own checklist asks admins to confirm that the whiteboards they needed did migrate. Users can check by finding the board in their OneDrive, under the Whiteboards folder.
- Expect questions about missing boards. A user who finds a board gone after 16 October cannot get it back. Tell the help desk so the answer is consistent, rather than a search for a restore that does not exist.
- Update internal guidance. Remove references to the standalone Whiteboard app from onboarding material and help desk documentation, and point users to Whiteboard in Teams.
