## Key points

- Microsoft’s cloud outage was still ongoing, with no full recovery estimate.
- An overwhelmed server process was contributing to capacity loss.
- Email, Teams and administration tools were affected.

## Summary

Microsoft had not yet restored its cloud services, and its attempted fixes had not delivered the expected improvement. The outage disrupted email and work tools for customers, while administrators also lost access to some services used to diagnose and manage the problem.

The incident began at about 18:00 UTC on 12 November and affected Exchange Online, Teams, Copilot 365, Defender for Office 365 and Intune. Microsoft said an overwhelmed core process was causing affected servers to stop responding and lose capacity; an alternative health check brought some servers back, but the company had given no timeline for full recovery.
