Microsoft 365 Outage Continues as Recovery Work Proceeds
Microsoft 365 remained disrupted on November 13, 2026, with Outlook, Teams and Copilot among the affected services. Microsoft said a patch had improved server stability in part of its infrastructure, while recovery work continued.
The outage started at approximately 18:00 GMT on Thursday, November 12. Its reach extended from Asia to the United States, affecting users and businesses as well as some government operations.
Microsoft said the disruption involved multiple Microsoft 365 services connected to Exchange Online and email. On its service-health page, the company continued to identify degraded service across both business or enterprise offerings and consumer products.
In its November 13 update, Microsoft said it was observing the results of the patch and working to apply it more broadly. The reported improvement concerned server stability in the portion of infrastructure where the change had been applied; the service-health page still showed disruption.
During troubleshooting reported on November 12, Microsoft had identified servers that were not passing automated health checks. The company's first efforts to restore those servers did not work immediately. Those findings concerned the recovery investigation rather than an established explanation for the outage.
Microsoft said it had no awareness of malicious activity responsible for the incident. That statement represented the company's position, rather than independent confirmation excluding such activity. The company said it would give a fuller account of the cause after mitigation.
