A widespread technical outage disrupted workplace communication and email services around the world on 12–13 November 2026, affecting users who rely on Microsoft 365 for their daily work.
The disruption affected Outlook, Microsoft Teams and other cloud-based productivity applications, leaving many users struggling to access their inboxes, send or receive emails, and use essential workplace tools.
What Happened During the Outage?
Reports from multiple regions indicated that the problems extended across several Microsoft services. Outlook users experienced difficulties accessing their mailboxes, while some users also reported connectivity issues with Teams, Copilot and other Microsoft 365 applications.

At the height of the disruption, outage-monitoring platforms recorded nearly 130,000 reports of Outlook-related problems. These reports indicate the scale of the disruption but do not represent the total number of people affected.
Why Were Users Experiencing Problems?
Initial technical updates pointed to infrastructure problems, including unexpectedly unavailable servers and increased load on the remaining systems. The precise cause was still under investigation as recovery efforts continued.
The disruption highlighted how technical issues within cloud infrastructure can affect multiple services used by businesses, educational institutions and public organisations.
Impact on Businesses and Employees
Email and online collaboration tools are central to modern workplaces. When these services become unavailable, meetings may be delayed, important messages can be missed, and teams may struggle to access shared documents or coordinate tasks.
The incident is a reminder that businesses should maintain alternative communication channels and have contingency plans for unexpected technology disruptions.
Service Recovery Efforts
Recovery work was underway as technical teams attempted to restore affected servers and improve service stability. Some services began recovering, although the experience varied across applications and users.
The outage also highlighted the importance of checking official service-status updates rather than relying entirely on social media reports during a developing technical incident.
