Microsoft outage disrupts Outlook, Teams and 365 for about 10 hours
What's new: Microsoft traced the disruption to unexpectedly unavailable servers, while Australia said it saw no sign of a cyberattack.
A widespread Microsoft outage disrupted Outlook, Teams and other Microsoft 365 services for about 10 hours on Thursday, affecting users across multiple regions and spilling into Friday in parts of Asia-Pacific. Downdetector showed reports peaking at more than 130,000 Outlook complaints in the US around 1 p.m. ET, with problems also logged in India, Australia and Japan. Microsoft said services tied to Exchange Online and email were hit after a number of servers became unexpectedly unavailable, putting strain on remaining infrastructure and causing some automated health checks to fail. The company shifted traffic, restored some servers and applied a broader fix. The US House of Representatives said its users were affected, and Australian agencies including the spy service and federal police were also caught up.
