Microsoft outage disrupts Outlook, Teams and Copilot worldwide
What's new: Microsoft linked the failures to overloaded infrastructure and servers that dropped out during automated health checks.
A widespread Microsoft outage disrupted Outlook email, Teams, Copilot and other Microsoft 365 services on Thursday, leaving users unable to send or receive messages or load inboxes. Downdetector logged nearly 130,000 Outlook problem reports shortly after 1 p.m. ET, while the BBC said users in 74 countries were affected. Microsoft said some Exchange Online mailbox connections in the Americas were hit after part of its infrastructure came under elevated load. The company later said several servers became unexpectedly unavailable after failing automated health checks and that it was testing a fix while using an alternative method to bring impacted servers back online.
