A global Microsoft 365 outage continues to affect Outlook email and some Teams features, as Microsoft began expanding the rollout of a patch on Friday. Microsoft said the patch has helped stabilize some servers, but it has not provided a timeline for service restoration. The company said the outage was caused by an overloaded process that handles secure connections and that there was no indication of a security breach. OpenAI and Anthropic reported issues with the Microsoft 365 connectors in ChatGPT and Claude. Government email services in the United States, Japan, and Singapore were also affected.
