Outlook outage: Microsoft reports 'issues' with Teams and email
Key Points:
- Microsoft reported issues affecting Exchange Online mailboxes and Microsoft Teams users, primarily in the Americas and North America, respectively, with disruptions confirmed through social media and outage monitoring site Downdetector.
- The Exchange Online mailbox problems stemmed from several servers becoming unexpectedly unavailable, causing strain on remaining infrastructure, rather than increased traffic volume.
- Microsoft has not identified any recent changes triggering the issue but suspects a specific component responsible for processing server health checks is involved, and steps have been taken to prevent further server impact.
- Mitigative actions have restored Microsoft Teams functionality, while efforts to resolve Exchange Online mailbox issues include pausing deployments, rerouting traffic, and restarting affected servers.
- The mailbox issue may affect Microsoft 365 service connectivity globally, and Microsoft continues to provide updates as it aggressively pursues solutions to reduce user impact.
