Microsoft 365 disruption hits Outlook, Teams and Copilot as recovery varies by region

Microsoft 365 disruption affected Outlook, Teams and Copilot, with recovery progressing unevenly across regions. The incident also disrupted third-party AI services that rely on Microsoft connectors and exposed how heavily organisations depend on Microsoft systems.

Microsoft said it had restored parts of its infrastructure in Asia Pacific and was gradually bringing traffic back, though some users still faced intermittent problems and capacity remained below normal. It extended the email timeout window to 48 hours while clearing delayed messages, said it had found no evidence of malicious activity, and promised a post-incident report. Reports also described NHS hospitals switching to pen and paper, with some appointments affected.
