Microsoft will release new Outlook for Windows usage and migration reports in the Microsoft 365 admin center. This update should enable organizations to track the adoption and usage of the new Outlook for Windows, providing detailed metrics on the number of active users transitioning from the classic version to the new one.
Timeline
The rollout should be completed by late March 2025.
Impact on your organization
After the rollout, the new Outlook for Windows usage and migration reports are available in the Microsoft admin center under Microsoft 365 apps > Usage. Don’t forget to add the necessary columns to your report view.
- Activity on classic Outlook
- Activity on new Outlook
Accounts with the Reports Reader role can export reports to CSV for the last 7, 30, 90 or 180 days.
The new Outlook migration report is similar to the previous Teams Classic vs. New Teams client usage report.
Usage and migration reports in Microsoft Graph
The new report information is not yet available in Microsoft Graph endpoints, including Beta endpoints.
Migration progress state
I found no endpoints to export this information via Microsoft Graph.
Activity for Outlook Classic and new Outlook
The endpoint getM365AppUserDetail does not yet include the new Outlook as platform information. The following Outlook platforms are currently included.
- outlook
- outlookMac
- outlookMobile
- outlookWeb
- outlookWindows
The Outlook app usage endpoints do not differentiate between Outlook Classic and new Outlook.
