After a period of extended monitoring, we’ve confirmed through customer reports and service health telemetry that the issue is resolved.

We’re continuing to conduct additional optimizations to further improve service availability, which remains in a healthy state. We’re monitoring telemetry closely while this work progresses to ensure service availability is fully restored.

We’re conducting additional optimizations to further improve service availability, which remains healthy. We’re closing in on a full mitigation to address any remaining impact and we’re closely monitoring telemetry to ensure this trend continues.

We’re continuing our period of monitoring service telemetry, which shows the service availability has remained healthy.

From monitoring service telemetry, most users should now experience relief. We’ve completed our optimizations and we’re continuing our period of extended monitoring to ensure the availability remains stable.

While we continue our period of extended monitoring, the availability of the Outlook on the Web service has reached expected availability levels. We’re continuing to optimize the environment to address the remaining impact.

We’re still addressing the remaining impact to the Outlook on the web service that is affecting some users. We’ve applied mitigation actions to reduce the mail queues and we’re continuing the extended period of monitoring to ensure stability continues.

We’ve isolated the cause of mail queue delays and have restarted the affected infrastructure to drain stalled queues. We’ll remain in an extended monitoring phase until this draining is completed and we can consider the incident fully recovered.

This quick update is designed to give the latest information on this issue.

We’re continuing to address lingering impact to the Outlook on the web service that is still affecting some users. In parallel, we’re investigating some mail queuing delays that is resulting in mail taking longer than expected to be delivered. Due to the impact of this incident, we will enter a period of extended monitoring prior to declaring this issue resolved.

We’ve started to deploy the fix which is currently progressing through the affected environment. While this progresses, we’re beginning manual restarts on a subset of machines that are in an unhealthy state.

We’ve identified a recent change which we believe has resulted in impact. We’ve begun to revert the change and are investigating what additional actions are required to mitigate the issue.

While we’re continuing the restarts to improve service availability, we’re thoroughly analyzing recent changes and the specific failure path to determine the next steps required to resolve the issue.
