Microsoft outage disrupts Outlook, Teams, and Microsoft 365 globally

Microsoft experienced a major outage Thursday afternoon affecting Outlook, Teams, Microsoft 365, and Copilot, with over 130,000 users reporting issues by early evening. The disruption lasted at least four hours before reports began declining. Microsoft attributed the problem to unexpected server unavailability straining infrastructure, not increased traffic. The company began redistributing connection traffic globally and restarting affected servers around 6:45pm to restore service. By 10pm, reported Outlook issues had dropped by more than half. Microsoft stated the outage could affect business and consumer users in any region, with Downdetector tracking similar spikes across its other services.
