Microsoft says its services have been broadly restored after a daylong global outage disrupted Outlook, Teams, Copilot and other Microsoft 365 applications across dozens of countries. The tech giant traced the disruption to an issue during an earlier network capacity upgrade that surfaced following a recent network change. Microsoft ruled out a cyberattack or AI agents as the cause and apologised to affected users. Businesses, schools, offices and airlines faced disruptions, with the company promising a full post-incident report.
