M365 User Information Hidden by Default
Reports provide information about your organization’s usage data. By default, reports display information with identifiable names for users, groups, and sites. Since September 1, 2021, Microsoft hides user information by default for all reports to help companies support their local privacy laws.
By default, user information will be shown as pictured below.
In order to view usernames within the Combine M365 reports, this feature can be disabled.
How to disable hidden usernames
Global administrators can revert this change for their tenant and show identifiable user information if their organization's privacy practices allow it.
It can be achieved in the Microsoft 365 admin center by following these steps:
- In the admin center, go to the Settings > Org Settings > Services page.
- Select Reports.
- Uncheck the statement In all reports, display de-identified names for users, groups, and sites, and then save your changes.
