Microsoft 365 outage hits Exchange, Teams and Copilot across the Americas
Kyrannio · x · 2026-11-13
On Nov. 12 Microsoft suffered a widespread disruption: users in the Americas couldn't access Exchange Online mailboxes, with elevated load on parts of its infrastructure causing connection errors. Microsoft is shifting traffic and rebalancing resources to restore service. Outlook, Teams, Copilot and other Microsoft 365 services were also affected, and Downdetector showed a surge in complaints — though the broader outage list circulating online isn't confirmed as one coordinated failure.
