Microsoft 365 Consumer

Our investigation so far indicates impact is associated with a possible third-party networking issue. We're recursively investigating the health of the Microsoft-managed service environment to identify whether any mitigation actions are required and ensure our services are healthy.

We’re analyzing available telemetry and user reports to determine cause of impact and develop a mitigation strategy.

We're continuing to investigate the failures, so that we can identify the root cause and determine the next steps to remediate the impact.

We're reviewing service telemetry data to gain insight into the underlying source of impact and determine our next steps.

A recent configuration change to update the sign in flow is resulting in some password-based sign in requests being blocked. We’re reverting the affected configuration to a previous healthy version and monitoring the service as the change propagates across affected environments to ensure successful restoration.

We've investigated a problem in which Teams Free users were unable to anonymously join Microsoft Teams Enterprise meetings and confirmed that service is now restored. We'll provide additional information in a closure summary within the "History" section of the "Service health" dashboard shortly.
