Microsoft said a global outage affecting services including Teams, Outlook and its Copilot AI software was not caused by a cyber-security incident, BBC reported. The disruption began on Thursday and continued into a second day on Friday, with users worldwide still affected. France 24 reported that Microsoft blamed server problems for the disruption as it struggled to fix them. Its tech correspondent Peter O'Brien said the outage's scale and duration could make it one of the biggest ever. The company has not given a fuller cause beyond ruling out a security breach.
