Microsoft outage disrupts Outlook, Teams, and AI tools globally

A major global Microsoft outage has disrupted services including Outlook, Teams, and AI tools, with nearly 140,000 reports of email problems peaking Thursday. Microsoft has ruled out a cyber-attack, but its fixes have been largely unsuccessful so far. The outage affects Microsoft 365 services, causing connectivity issues for email, calendars, and files, though some users report normal Teams access. Over 430 million people use these apps, and the disruption has impacted companies, governments, and AI firms like OpenAI and Anthropic. Microsoft attributes the issue to elevated server load, where many servers became unexpectedly unavailable, straining remaining ones. Experts warn the outage has far-reaching effects on work and daily tasks, with companies losing a full business day as restoration efforts continue.
