A global Microsoft outage on Friday the 13th disrupted services including Outlook, Teams, Microsoft 365, OneDrive, Copilot, and the Microsoft Store. At its peak, DownDetector logged over 130,000 Outlook outage reports and 46,000 for Microsoft 365. Microsoft said a core process on affected servers became overwhelmed, causing them to stop responding, and ruled out a cyberattack. Recovery was described as gradual.
