Current status: We're continuing to work through restarting and validating the affected servers to safely return them to service, and we're exploring opportunities to expedite this process. In parallel, we're assessing whether reverting the small number of recent configuration updates we identified could help accelerate recovery.

Previous status: We've validated an alternative health check method on a subset of affected infrastructure, which allowed the servers in that subset to successfully return to service, and we're now applying this change more broadly. We're also preparing an automated recovery process to continually detect and restart unresponsive servers, to help keep them in service while this change progresses. Additionally, our review of recent changes has identified a small number of configuration updates that we're investigating as potential contributors to the issue.

Scope of impact: This issue may affect users attempting to access the affected Microsoft 365 services.

In an official update, Microsoft said the disruption was affecting several Microsoft 365 services, including Exchange Online, Microsoft Teams, SharePoint Online, Microsoft Copilot 365 and Microsoft Defender XDR. The company said the affected infrastructure was experiencing elevated loads across multiple regions, likely contributing to connectivity errors.

Microsoft said it was restarting and repairing affected parts of its infrastructure to restore capacity. It is also investigating an unexpected increase in a specific type of service traffic to determine whether it is contributing to the elevated load. The company is evaluating options to redirect traffic to alternate infrastructure to speed up recovery.

Microsoft said the issue could affect users attempting to access the impacted services. Its next update was scheduled for Thursday, November 12, 2026, at 8:30 PM UTC. (3:30 PM EST)

Microsoft is reporting issues affecting Exchange Online and Microsoft Teams across the Americas. Users may experience email delivery delays or find that messages remain in the Drafts folder.
