Microsoft suffered an outage disrupting Outlook, Teams and other services
Microsoft’s outage disrupted Outlook, Teams, Copilot and other Microsoft 365 services Thursday, causing connectivity problems in multiple regions. The company said unexpectedly unavailable servers strained its remaining infrastructure; it was working to restore service but gave no full-restoration time. Downdetector showed over 130,000 users reporting Outlook problems midday; reports across Microsoft apps had nearly halved by 4 p.m. Eastern.

Microsoft initially described elevated load, then said it was caused by unavailable servers rather than increased traffic. BleepingComputer reported that the company paused deployments, redistributed connection traffic and restarted affected servers. Signals AZ said Microsoft was testing an alternative system for checking server health and making progress in returning some servers to operation as recovery continued.
