Microsoft apologises for near two-day Outlook and 365 outage, blames a network upgrade

The outage began on Thursday with Exchange Online, Microsoft's email backend. Gizmodo says Downdetector logged reports from 74 countries and territories, with about 130,000 Outlook reports at the peak. Teams, SharePoint Online and Copilot were also hit, and Ars Technica reports that governments, hospitals and courts were disrupted. On Friday Microsoft apologised and said it was seeing broad recovery. It says the cause was a technical issue from an earlier network capacity upgrade, not an attack or AI agents. The Verge's sources link it to network configuration changes in Azure, Microsoft's cloud. Microsoft will publish a full report.

Do anything? No. Mail may arrive late for a while, but Microsoft says it found no sign of malicious activity.
