Microsoft 365, Outlook, and Teams outage disrupts US users and AI services

economictimes.indiatimes.com — November 12, 2026 at 10:01 PM UTC

Microsoft 365, Outlook, Teams, and Copilot experienced a major outage on Thursday, disrupting thousands of US users and also affecting AI services from OpenAI and Anthropic that rely on Microsoft connectors. Microsoft attributed the issue to elevated load on its infrastructure, which caused servers to fail during automated checks, leaving them unexpectedly unavailable. The company paused deployments, restarted affected servers, and tested a fix, while OpenAI and Anthropic separately reported investigating broken connections with the Microsoft 365 connector. Earlier in the day, Microsoft said it had resolved a separate Teams disruption in North America, though some users still reported connectivity issues. The company did not immediately provide further details on the root cause of the server failures.
