getMailboxUsageDetails returning a ID instead of UserprincipalName and DisplayName 21 Reputation points


Very recently this query has started to output a ID instead of actual users UPN and DisplayName. This used to output the proper UPN and DisplayName.
Anybody know what this ID is and if it's able to query Exchange/Azure/M365 to get the actual UPN and DisplayName?'D7')?$format=application/json

The same result shows for different tenants.
