[Whiteboard] Legacy Whiteboard migration to OneDrive

Microsoft Whiteboard is migrating from legacy Azure-based storage to OneDrive-backed storage. Migration must be completed by September 25, 2026; afterward, legacy Whiteboards become read-only until October 16, 2026, when they will be permanently deleted. Admins should inventory, notify users, and ensure migration before deadlines. 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 dates Before September 25, 2026: Users can still trigger migration, retry failed migrations, and export important content. September 25, 2026: Migration tooling is retired.
