Microsoft outage disrupts Outlook, Teams, and Copilot for thousands of users

A major Microsoft services outage on Thursday, November 12, disrupted access for thousands of users, primarily affecting Outlook, Teams, and Copilot, with the company working to restore services. The outage, particularly widespread in the Americas, saw over 130,000 reports of Outlook issues, including login failures and email delays, plus over 46,000 for Microsoft 365 and about 3,000 for Teams. Microsoft attributed the problem to higher-than-usual load on its infrastructure, causing connection errors. Microsoft is redistributing traffic across its infrastructure nodes to ease the load and restore connectivity. It confirmed service restoration for Teams in North America, though some users still reported issues, and the company has not yet provided a full cause or total affected user count.
