They have reverted the offending configuration and restarted the affected infrastructure, which after a period of monitoring has remediated impact. However, users still facing failures may need to follow the instructions in the ”More Info” section of this event to experience full relief.

Scope of impact : Any users serviced by the affected infrastructure who are attempting to utilize the Mobile Device Management feature may be impacted.

Root Cause : An authentication component within the affected infrastructure was resulting in impact.

Next steps : Microsoft are reviewing their network authentication component configuration procedures to find ways to prevent this problem from happening again.
