On January 22, 2026, Microsoft suffered a major outage that disrupted Outlook, Microsoft 365, Teams and related services for thousands of users, particularly across North America. Downdetector showed tens of thousands of reports at the peak, with users unable to send or receive emails or access collaboration tools. Microsoft said the issue stemmed from a portion of its service infrastructure not processing traffic as expected and worked to rebalance and restore systems. Services gradually returned after about eight hours, though recovery continued.
