Microsoft is working to restore its services following a major global outage that has disrupted access to Outlook, Microsoft Teams, OneDrive and Copilot since Thursday, November 12.

The disruption has affected businesses, government agencies and millions of users across several countries. Users have reported difficulties accessing emails, sharing files and using essential workplace applications.

Microsoft attributed the incident to infrastructure problems that left several servers unexpectedly unavailable, placing additional pressure on its remaining systems. The company said there was no indication that the disruption was caused by a cyberattack.

In its recovery efforts, Microsoft has deployed infrastructure patches to improve server stability and restore affected services. The company reports positive progress but acknowledges that some users may continue experiencing intermittent disruptions.

The incident highlights the growing dependence of businesses and public institutions on cloud-based services and the widespread operational consequences of disruptions to major technology platforms.
