Microsoft outage disrupts Outlook and Teams for users worldwide

Microsoft is working to resolve a widespread outage affecting tens of thousands of users globally, impacting services including Outlook, Teams, and Copilot, with reports peaking at nearly 20,000 per minute. The outage began just before 5am AEDT, with nearly 130,000 users on Downdetector reporting issues accessing emails and loading inboxes across 74 countries. Microsoft restarted unresponsive servers after validating a fix, using an alternative health check method to restore functionality. Microsoft identified "a small number of configuration updates" as potential contributors to the issue, though investigations continue. The company is preparing an automated recovery process to detect and restart other affected servers as it applies the fix more broadly.
