Updated August 28, 2026: We have updated the timeline. Thank you for your patience.

[Introduction]

To streamline and modernize reporting experiences across Microsoft 365, we are retiring the Outlook for Windows Usage Report in the Exchange admin center (EAC). Admins can continue accessing Outlook usage information in the Microsoft 365 admin center (MAC), which offers a more complete and up‑to‑date reporting experience across Microsoft 365 apps.

[When this will happen]

Retirement will begin in early November 2026 (previously mid-August).
Retirement will complete in late November 2026 (previously mid-September).

[How this affects your organization]

Who is affected

Admins who use the Exchange admin center (EAC) to view Outlook for Windows usage data.

What will happen

The Outlook for Windows Usage Report will be removed from the EAC.
No replacement Outlook usage reporting will remain in the EAC after this retirement.
Admins can continue accessing Outlook for Windows usage insights through the Microsoft 365 admin center (MAC): Reports > Usage > M365 Apps > Usage > Outlook for Windows
MAC provides consolidated usage reporting with charts and tables to help admins understand usage patterns across Outlook and other Microsoft 365 apps.
No impact to Outlook for Windows functionality for users.
This report retirement will occur automatically; no opt‑out or admin toggle will be available.

[What you can do to prepare]

No admin action is required.
If your organization references the EAC usage report in documentation or internal processes, update those materials before the retirement is complete.
