Microsoft 365 and Outlook restored after nearly 24-hour global outage
Microsoft 365, Outlook, Teams, Copilot and over ten other services went offline for nearly a day, affecting users in at least 70 countries. The company attributed the disruption to problems during an earlier network capacity upgrade and ruled out cyberattacks and AI agents as causes. Services returned around 3 p.m. ET on Friday, with recovery carried out in stages and stability checked at each step. Organizations including businesses, governments, schools, courts and UK NHS staff were affected, and some Japanese firms temporarily reverted to fax. Microsoft has apologized, said emails held during the outage will be queued for up to 48 hours, and plans to publish a full post-incident report.
