reportRoot: getOffice365GroupsActivityDetail how is the 'Owner Principal Name' determined?

Question

In the reportRoot:getOffice365GroupsActivityDetail API, how is the "Owner Principal Name" calculated? Is this the account that initially created the Microsoft 365 group?

I've noticed that the "Owner Principal Name" differs from the "Managed By" field when pulling group data via the Get-UnifiedGroup cmdlet. Additionally, this value doesn't appear in the "owners" attribute when using Get-MgGroup. I'm curious to understand how the "Owner Principal Name" is determined and if there's a way to query this information directly, without relying on the report.

Hello Wrigley, Jonathan,

Thank you for reaching out to Microsoft Support!

Microsoft 365 reports show anonymous user names, group names instead of the actual group names in the following reports:

• Email Activity
• Mailbox Activity
• OneDrive files
• SharePoint Activity
• SharePoint Site Usage
• Microsoft Teams Activity
• Viva Engage Activity
• Active users in Microsoft 365 Services and Apps
• Groups Activity

Microsoft is hiding user information by default for all reports as part of ongoing commitment to help companies support their local privacy laws.

To fix this issue, change the following setting in the Microsoft 365 admin center.

1. Go to the Microsoft 365 admin center.
2. Go to Settings > Org Settings > Services.
3. Select Reports.
4. Clear Display concealed user, group, and site names in all reports, and then select Save.

Note: You must be a Microsoft 365 global administrator.

Please refer to documentation.

Hope this helps.
