Microsoft 365 services recover after global outage disrupts businesses

Microsoft is gradually restoring Microsoft 365 services after a global outage that disrupted businesses for over 24 hours, with broad recovery reported as of Friday, Nov. 13, though some Exchange Online-related degradation persists. The outage, which began more than a day prior, was caused by a technical issue from an earlier network capacity upgrade, not a cyberattack or AI. Affected functions include email delays, Copilot 365 Chat, Microsoft Teams, and some Admin Center pages. Experts warn cyber criminals may exploit the disruption through social engineering, urging vigilance against fake password resets or multi-factor authentication requests. Microsoft has apologized and promised a full post-incident report.
