# Widespread Microsoft 365 Outage Disrupts Multiple Services

by Lauren Palmer

 November 12, 2026

### Microsoft is working to restore access to several major cloud services following widespread connectivity failures.

Microsoft 365 users across multiple regions experienced widespread connectivity issues on November 12, disrupting access to Outlook, Teams, SharePoint Online, and other cloud-based applications.

According to Downdetector, more than 130,000 outage reports were recorded by approximately 2 p.m. Eastern Time, with users reporting difficulties accessing email and sending or receiving messages.

Microsoft confirmed that additional services may also be affected, including Exchange Online, Microsoft Teams, SharePoint Online, Microsoft 365 Copilot, Microsoft Defender XDR, Planner, To Do, Intune, Defender for Office 365, Power BI, and several Microsoft Purview services and Microsoft 365 Apps Admin Center services.

Microsoft initially attributed the disruption to servers unexpectedly becoming unavailable, placing additional strain on remaining infrastructure. The company paused deployments, redistributed traffic, and began restarting affected servers. In its latest update, Microsoft acknowledged that recovery efforts have not delivered the anticipated relief.

"Our investigation has found that a core process on the affected servers is becoming overwhelmed, which causes the servers to stop responding and contributes to the capacity loss." Microsoft said. The company is now isolating a portion of the infrastructure, restarting affected components, and gradually reintroducing traffic to validate service stability.

Microsoft has not provided an estimated time for full restoration.
