Microsoft says the Project usage report in the Microsoft 365 admin center is scheduled to become unavailable starting December 4, 2026. Administrators who rely on it should export the data they want to keep before November 20, 2026. Notice MC1539001 places the report under Reports > Usage and says it counts users active in the Project desktop client, Project Online and Project for the web. Read the archived copy of notice MC1539001.
What administrators should export
Export any Project usage data your team needs to retain before November 20. Once the report becomes unavailable, its historical data will no longer be accessible in the Microsoft 365 admin center. Microsoft also advises updating internal documentation and processes that refer to the report.
Treat reviewing the Planner report as a separate task from exporting Project usage data.
What the change leaves in place
The notice says the report retirement will not affect the Project desktop client’s features, support or project files. The Planner usage report covers activity in Planner and Planner premium, while the Project report counts activity across the desktop client, Project Online and Project for the web.
