Microsoft outage disrupts Outlook, Teams, and Copilot for global users
Microsoft experienced a major outage affecting multiple services including Outlook, Teams, Copilot, and OneDrive, impacting users worldwide on Thursday, November 12. Over 90,000 users in the US reported access issues with Outlook by 8 PM, with more than 2,000 reports logged in France by 9:30 PM. Microsoft 365 confirmed the incident on X, initially investigating Exchange Online mailbox access problems in the Americas before acknowledging potential connectivity issues for all regions. The company attributed the outage to the unexpected decommissioning of servers causing high load, not increased traffic, and was working to limit impact. Earlier that day, Microsoft had resolved a separate Teams outage affecting North American users. OpenAI also reported investigating issues related to Microsoft connectors that could interrupt new connections and cause tool malfunctions.
