Microsoft 365 outage disrupts Exchange Online; cause still open
Original title: Microsoft Outage 2026: What Happened and What the Law Says
As of 11:01 UTC on November 13, Microsoft reported partial recovery and no evidence of malicious activity.
A Microsoft outage that began on November 12 disrupted Exchange Online and connected Microsoft 365 services in multiple countries, affecting businesses, government agencies, courts, and financial institutions. Disruption continued into November 13, when Microsoft reported partial recovery but not full restoration. Technical signs pointed to connection-handling, unavailable servers, and authentication and routing components; Microsoft investigated configuration changes and applied recovery steps. A legal commentary says DORA, UK supplier rules, and an Australian arrangement may apply, but an outage does not by itself prove negligence or noncompliance.
Unconfirmed: Microsoft had not completed its root-cause investigation, and the commentary does not establish legal liability.
- The outage began on November 12 and was still being recovered on November 13.
- Microsoft’s 11:01 UTC update found no evidence of malicious activity.
- The final root-cause investigation was still incomplete.
- Affected users included courts and financial institutions, not only businesses.
