Microsoft outage disrupts Outlook email services worldwide

A worldwide Microsoft outage has disrupted Outlook email services since Thursday evening, leaving many users unable to send or receive messages on Friday morning. Microsoft Teams and the Copilot AI assistant were also temporarily affected. Microsoft reported progress before 9 a.m. after optimizing data traffic, and outage reports declined, though no all-clear was given. Users could see email subjects but not open contents or attachments. The company found no evidence of a cyberattack. Downdetector recorded nearly 130,000 Outlook problem reports by Thursday evening. Microsoft is working to stabilize services and plans to publish a detailed report on the cause. A similar large-scale outage occurred in late August.
