Title: Some users are seeing incorrect presence status in Microsoft Teams
User Impact: Users are seeing incorrect presence status in Microsoft Teams.
More info: Users may see presence status as 'offline' or 'unknown.'
Current status: We're analyzing service telemetry showing presence availability so we can better understand the origin of impact and determine our next troubleshooting steps.
Scope of impact: Your organization is affected by this event, and a subset of users may experience impact.

More info: Users may see presence status as 'offline' or 'unknown.'
Current status: Our analysis of service telemetry in parallel with assessment of newly implemented changes made to the service suggests that a recent update intended to optimize presence functionality may inadvertently be contributing to impact. We're continuing to verify this theory and are simultaneously determining our next steps to provide alleviation.
Scope of impact: A subset of users hosted out of the affected infrastructure may experience impact.

More info: Users may see presence status as 'offline' or 'unknown.'
Current status: We've identified through further investigation that the aforementioned presence update caused a discrepancy between the information needed to propagate users' presence and the cache information currently available, consequently inhibiting users from seeing correct presence across all Microsoft Teams connection methods. To alleviate impact, we've developed, tested, and initiated the deployment of an update to resolve the cache issue by eliminating the impacting discrepancy. We'll provide additional information regarding the fix's deployment status and estimated time to resolution via our next scheduled update.

More info: Users may see presence status as 'offline' or 'unknown.'
Current status: We've confirmed via service telemetry that our change addressing the cache issue has already brought alleviation to a large portion of formerly affected users. We're continuing to monitor its deployment to confirm resolution of persisting impact, and we anticipate full remediation for all users by our next scheduled update.
