Microsoft 365 outage: tens of thousands of users left without Outlook, Teams and Copilot
On November 12, 2026, Microsoft reported a large-scale outage affecting Outlook, Teams, SharePoint, Copilot and other Microsoft 365 services. The company attributed the problem to servers unexpectedly becoming unavailable, rather than a surge in traffic, and carried out recovery work by redistributing traffic and restarting equipment.
