MS365 Some Reports Showing GUID

Mark Quinn 6

Every month I create usage reports from our MS365 Business tenant. Today for some reason, some of the reports are showing the GUID instead of the recognisable usernames.
I have confirmed that the setting to de-identify names is not switched on. SharePoint report is not affected as are some others but OneDrive and email reports are both doing it so i cannot complete the reports.

I have the same issue. Something changed yesterday. Using the getOneDriveUsageAccountDetail endpoint I just get GUIDs for ownerDisplayName, ownerPrincipalName, and siteURL.

Please check the M365 reports section and see if it has any differences/ discrepancies then open support ticket in the M365 portal itself.

I do have the very same issue, but I'm using this MS Graph URL https://graph.microsoft.com/v1.0/reports/getOffice365ActiveUserDetail(date=2021-08-25), Yesterday started that issue, in the past we had issues where the API delivers an empty file, and the next day all good, but for this case we still receive GUIDs instead of Email and Principal Name.

@Ricardo Arias we are seeing the same thing in our tenant. Have MS offered up any explanation? To clarify User Principal Name and Display name now showing guides instead of the UPN etc. This was working fine up until a few days ago...

We found that this was an intentional change by Microsoft. buried in an announcement in the message center (MC275344), which did not identify it as a breaking change. They offered the lame excuse that it was to 'enable your company's privacy policy.' In my mind, enabling is not the same as unilaterally making the change for all companies that don't need it.

"Global administrators can revert this change for their tenant and show identifiable user information if their organizations privacy practices allow. This can be achieved in the admin center by going to the Settings > Org Settings > Services page and selecting ‘Reports’. Under ‘choose how to show user information’, select ‘Show identifiable user information in reports’. Showing identifiable user information is a logged event in the Microsoft 365 Compliance Center Audit log."

@Chuck Boeheim thanks very much for this. Yeah, I mean by all means give the option but crazy to enforce. Like many companies we use that data for a lot of quite business critical activities (licensing users etc). Anywho thanks for the help and I'll change that setting on our tenant.

This must be related to the privacy changes - https://techcommunity.microsoft.com/t5/microsoft-365-blog/privacy-changes-to-microsoft-365-usage-analytics/ba-p/2694137 to hide user identifying info in the reports until explicitly disabled by the admin.

Follow the screenshot below from the Admin Portal.
