More info : Users could also have reviewed for updates on this investigation.

Final Update : 12/06/2023 09:14:00 AM – After a period of monitoring service telemetry, Microsoft have confirmed that the services are operating in a stabilized state following the load-balancing procedures, and users are no longer experiencing impact.

Scope of impact : This issue could have affected any user attempting to access the Microsoft Intune and Windows 365 services.

Root cause : A sudden influx in network traffic reduced the effective capabilities of Microsoft request management systems, temporarily resulting in access issues for users attempting to access Microsoft Intune and Windows 365 services and functions.

Next steps : Microsoft are continuing their active monitoring for evidence of additional impact from this event to ensure swift response and mitigation.

They are working to further refine the traffic balancing systems to more effectively recover from events of this nature.
