An Associated Press article on NBC News reports that a widespread outage hit Microsoft platforms including Outlook on Nov. 12, 2026, leaving many users unable to send or receive email and causing errors across Microsoft's app suite. More than 120,000 users reported Outlook problems on Downdetector by around 1:30 p.m. ET, thousands flagged issues with Teams, Copilot, and Microsoft 365, and Microsoft said it was investigating, citing elevated load on part of its infrastructure and planning to redistribute traffic.
