Microsoft reports progress on global Outlook outage, but issues persist

A global Microsoft outage on November 13, 2026, is disrupting Outlook email services for millions of users worldwide, with the company reporting progress but no full resolution yet. Microsoft says it has improved service stability by optimizing data traffic and is expanding these measures to more regions. While some users can access their inboxes, many still cannot open emails or attachments, and sending and receiving messages remains problematic. The company has found no evidence of a cyberattack and will publish a detailed report on the cause after fixes are complete. The outage has also affected Microsoft Teams and Copilot, and has impacted email services at Deutsche Bahn and Lufthansa.
