Some Users not able to see Presenece information in Teams Tuesday 5th May 2020 02:45 PM

The Systems group started receiving questions regarding presence information not updating for some users in Teams. As we were looking into this, Microsoft has reported an Incident, TM212081, and they are investigating the issue.

Impact: Presence information may not be correct for Teams users.

Affected Applications: Microsoft Teams

As of 8:05PM on 5/5/2020, Microsoft reports that the presence issue was fixed and presence is working as expected.

Root cause: A recent configuration change resulted in a spike of memory utilization on infrastructure that handles user presence requests and updates.

Final status: After reverting the configuration change, we completed the process of rerouting traffic and restarting the impacted infrastructure. Our monitoring and testing of the service indicates that the service is stable and presence is working as expected.
