Microsoft has apologized for a global service outage that disrupted millions of users worldwide, saying the incident was triggered by an earlier network capacity upgrade and was unrelated to cyberattacks or AI agents, according to CCTV News.

The company said it could not give a timeline for full service restoration. Earlier updates described recovery progress as "encouraging," while engineers were working to clear residual impacts from the failure.

The breakdown took down Teams, Outlook and its AI-powered Copilot across at least 70 countries.

Microsoft also warned users they may continue to face intermittent access issues.

Public services across multiple nations felt the ripple effects. Britain's NHS said the disruption inevitably caused disruption for staff, though appointments remained on track.

Some schools switched to phone-only contact with parents. US federal government agencies and court systems also reported service problems.
