Microsoft says it has finally restored its Microsoft 365 services after an outage that affected Outlook, Teams, Copilot, and other apps for more than a day. The company posted on X on Saturday, November 14, to confirm that services had been restored for the remaining affected customers and regions. The outage lasted well over 24 hours and affected businesses and government agencies around the world.
As we reported yesterday, the problems started with Exchange Online at around 11:17 a.m. ET on November 12. A wider Microsoft 365 outage followed at 1:26 p.m. ET. Microsoft had been trying to get the affected servers back online since then, but some of its recovery attempts were unsuccessful.
What caused the outage?
Microsoft initially suspected unusually high traffic was behind the problems. However, further investigation found that several backend servers had unexpectedly become unavailable, leaving the remaining ones struggling to handle the traffic.

The company tried restarting some of those servers, but they became unresponsive again once traffic returned.
