Microsoft Whiteboard is migrating from legacy Azure-based storage to OneDrive-backed storage.

[What and why:]Microsoft Whiteboard is completing its transition from legacy Azure-backed storage to OneDrive-backed Whiteboards. Organizations that still have legacy Azure-based Whiteboards must migrate them to OneDrive-backed storage before migration tooling is retired - September 25, 2026. After September 25, 2026, remaining legacy Azure-based Whiteboards become read-only and can no longer be migrated and can be only exported until October 16, 2026. After October 16, 2026, any remaining legacy Azure-based Whiteboards will be permanently deleted and cannot be recovered.Key datesBefore September 25, 2026: Users can still trigger migration, retry failed migrations, and export important content.September 25, 2026: Migration tooling is retired. Remaining legacy Azure-based Whiteboards become read-only and can no longer be migrated, but can still be viewed and exported until October 16, 2026.October 16, 2026: Remaining legacy Azure-based Whiteboards are permanently deleted and cannot be recovered.November 30, 2026: Legacy Azure Whiteboard service shuts down.[Rollout schedule:]General Availability (Worldwide, GCC, GCC High, DoD): We will begin rolling out on late September 2026 and expect to complete by mid-October 2026.[Impact on your organization:]This change impacts organizations that still have legacy Azure-based Microsoft Whiteboards that have not yet been migrated to OneDrive-backed storage.After September 25, 2026:Users will no longer be able to migrate remaining legacy Azure-based Whiteboards.Remaining legacy Azure-based Whiteboards become read-only and can no longer be migrated, but can still be viewed and exported until October 16, 2026.Organizations that have not completed migration risk losing access to business content stored in legacy Whiteboards.After October 16, 2026:Any remaining legacy Azure-based Whiteboards will be permanently deleted and cannot be recovered.Enterprise users should access Microsoft Whiteboard through Teams and supported web experiences.Organizations that have already completed migration to OneDrive-backed Whiteboards will not experience changes to existing OneDrive-backed content. New Whiteboards are already created in OneDrive-backed storage.[Action required / Recommendations:]Admins should take the following actions immediately:Inventory remaining legacy Whiteboards: Use the WhiteboardAdmin PowerShell module to identify Azure-based Whiteboards that still require migration.Communicate with affected users:Notify Whiteboard owners of the migration deadline (September 25, 2026) and deletion deadline (October 16, 2026).Encourage users to migrate, export, or preserve any business-critical content before the deadlines.Validate migration completion: Review migration status and confirm that important Whiteboards, permissions, and user access have been successfully migrated and remain accessible in OneDrive-backed storage.Plan for large-scale migrations: For inactive users, orphaned Whiteboards, or large migration volumes, consider using the administrator-driven migration approach documented by Microsoft Whiteboard engineering.Update internal guidance: Update user training materials, help documentation, and support procedures to direct users to Microsoft Whiteboard in Teams and supported web experiences rather than standalone applications.Act before migration tooling is retired: After September 25, 2026, migration tooling will no longer be available, and no further migration path will exist for remaining legacy Whiteboards.
