Teams status is showing as 'status unknown'

[JamesDay]

We are seeing a strange issue where users of Teams have their status shown as 'status unknown'. In our organisation this only seems to be affecting users who are using Teams on MacOS. Users have tried signing out/back in, restarting their Macs, and also reinstalling Teams.

My organization has been seeing the same issue today as well. Hopefully they are aware and looking into it. @JamesDay

Title: All users can't view or update user presence in Microsoft Teams

User Impact: Users are unable to view or update user presence in Microsoft Teams.

More info: Users will see a "Status Unknown" message when attempting to view another users' status. Current status: We've performed additional analysis and determined that failing over traffic to alternate infrastructure will be a more efficient mitigation strategy. We'll continue to monitor service health while this process completes.

Scope of impact: This issue may potentially affect any of your users attempting to look up or update user presence.

Start time: Tuesday, May 5, 2020, 12:21 PM (7:21 PM UTC)

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

@JamesDay we are experiencing similar symptoms where most users show as "status unknown".  We're running Teams across multiple Windows desktops and Android devices.
