Microsoft still working to fix major Teams and Outlook outage

Microsoft is still working to resolve a major outage affecting its Teams and Outlook services, which has disrupted users worldwide since Thursday. The company has applied additional mitigation measures but is encountering issues implementing some changes. Microsoft attributed the problems to server and connectivity issues, and said it does not believe the outage was caused by a cyberattack. Downdetector showed nearly 50,000 user reports of problems with Microsoft 365 overnight, with services impacted from the Asia-Pacific region to the Americas. The outage has disrupted various public and private institutions, including some U.S. and Australian government services, as well as AI startups OpenAI and Anthropic. Microsoft thanked users for their patience while it works urgently to resolve the incident.
