Microsoft outage hits Outlook, OneDrive, and Copilot worldwide

Microsoft is experiencing intermittent outages affecting Outlook email and other services like OneDrive, Copilot, and Teams since Thursday, November 12, with users receiving error messages when trying to access their accounts. The company attributes the disruption to an unexpected unavailability of some servers, which is overloading the remaining infrastructure. Microsoft has restarted affected servers and is implementing traffic adjustments, but reports indicate services are recovering only partially and inconsistently across regions. Microsoft has ruled out a cyberattack, according to executive Charles Lamanna. Downdetector recorded over 130,000 outage reports for Outlook and 50,000 for Microsoft 365, while users have taken to social media with the hashtag #Outlook, and employers are concerned about productivity losses.
