Issue Status : RESOLVED

Issue Description : Azure Active Directory Identity Protection Alerts through Microsoft Graph may not return the expected fields

More Information : Customers may notice that the “userPrincipalName” property is no longer returned for certain requests and alerts.

Final Update : 16/03/2023 07:25:00 AM – Microsoft have identified and deployed a fix to address the issue and users should now see new alerts containing UPN information as expected. 

Root cause : The behavior change occurred as a result of a nested dependency, which the Microsoft Graph Security API depends on to make the UPN available to API clients.

The nested dependency was decommissioned as part of a necessary configuration change. At the time of decommissioning, the nested dependency was not identified and subsequently resulted in impact.
