Microsoft outage disrupts Teams, Outlook and other services

Microsoft first acknowledged the outage at 12:54 p.m. ET through its Microsoft 365 Status account on X. An update at 1:07 p.m. said the issue could affect Microsoft 365 connectivity in any region, after an initial notice focused on email inboxes in the Americas. The company said it was redistributing connection traffic across its worldwide infrastructure to balance the load.

Microsoft said it had paused deployments and configuration changes while checking whether recent changes were connected to the outage. It also moved traffic away from affected infrastructure, with further traffic shifts underway, and began restarting affected servers. In an update posted at 2:50 p.m. ET, the company said it was testing a configuration change after servers began failing automated health checks and becoming unavailable.

The disruption also made Microsoft’s usual support channels difficult to reach. The company warned that some customers might not be able to access the Microsoft 365 admin center and directed them to its service status webpage. That webpage was also unavailable for part of the day, according to Mashable reporters. At 3:10 p.m. ET, Microsoft said it was deploying multiple mitigations to restore service.

Downdetector showed a sharp increase in user reports involving Teams, Outlook, Copilot AI, Microsoft 365, Azure and the Microsoft Store. Microsoft’s service health updates said the incident affected business and enterprise customers, rather than its consumer technology products. Microsoft had not responded to Mashable’s questions at the time of publication.
