Multi-geo - preferredDataLocation of users and Microsoft 365 groups compared with usage location (heuristic).

Required Microsoft Graph permissions

User.Read.All Group.Read.All — application permissions, granted to the app registration with admin consent.

Licence: Microsoft 365 Multi-Geo add-on (the report is empty otherwise).

Endpoints: GET /v1.0/users?$select=preferredDataLocation,usageLocation,country · GET /v1.0/groups?$select=preferredDataLocation

If a permission is missing, this report shows a red load error with the Graph status code — not an empty table.

Multi-geo Data Location

In a Multi-Geo tenant, preferredDataLocation decides where a user's mailbox and OneDrive, and a group's site, are stored. Unset means the central geo. For data-residency obligations that is a compliance question, not a technical one - this report shows where the data is and where the user is.
