Microsoft is retiring legacy Education LTI tools (Teams Assignments, OneDrive, OneNote Class Notebook, Reflect) on September 17, 2026, replacing them with a unified Microsoft 365 LTI tool. Education tenants must transition, update documentation, and notify users; no admin action is needed to remove legacy tools.
Applies to: Microsoft 365 apps
