Microsoft outage spreads beyond Outlook to Teams, SharePoint, Copilot and Defender XDR
Kyrannio · x · 2026-11-13
Microsoft's outage now reaches far beyond Outlook: Teams, SharePoint, Copilot and even the Defender XDR security platform are hit, and consumers can't reach OneDrive or Office on the web.
Microsoft first blamed elevated load, then said a large number of its servers became unexpectedly unavailable, dumping their load onto the rest — without explaining why. It is restarting servers with a fix, investigating high processor use, and has paused all deployments. Users note that organizations that moved everything to Microsoft are now stuck with broken notifications and non-working systems.
