## Timeline of updates

- **investigating** 2026-11-12 21:01 UTC: User impact: Users may be unable to connect to multiple Microsoft 365 services. More info: More info: Potentially impacted services include: - Exchange Online - Microsoft Teams - SharePoint Online - Microsoft Copilot 365 - Microsoft Defender XDR - Microsoft Planner - Microsoft To Do - Microsoft Purview: Multiple Purview services including Authorization, Auto Labelling, Data Loss Prevention (DLP), Communication Compliance, and Data Classification are impacted. Current 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. Previous status: While validating the targeted change, we found that many of the affected servers have become unresponsive, which is preventing us from confirming whether the change is effective. We're restarting these servers so they can come back online with the change in place, and we're applying the same approach to additional affected portions of our infrastructure to validate the results more broadly. Scope of impact: This issue may affect users attempting to access the affected Microsoft 365 services. Next update by: Thursday, November 12, 2026, at 10:30 PM UTC
