Microsoft reports ongoing outage affecting Outlook, Teams and Copilot
Microsoft said a global outage of its Microsoft 365 services, including Outlook, Teams and Copilot, persisted into the evening as the company worked to restore connectivity.
Microsoft confirmed that a worldwide disruption of its Microsoft 365 services began on Thursday, affecting Outlook, Teams and the Copilot AI assistant. The company attributed the problem to elevated load on its infrastructure and said the issue spread to users in 74 countries and territories within an hour, according to outage tracker Downdetector.
Initial statements indicated the problem was being investigated in the Americas, but Microsoft later clarified that connectivity errors were occurring for users in all regions. In a post on X, the company explained that a portion of its infrastructure was experiencing elevated load across multiple regions, contributing to the errors.
Microsoft said it had paused new deployments, redirected traffic away from the affected servers and restarted those servers to restore service. By early afternoon Eastern Time, about 130,000 users in the United States reported Outlook problems, with the number falling to roughly 37,000 by early evening as reports declined.
Updates posted by Microsoft on X indicated that, while some capacity was being restored, users might see a gradual recovery as their clients reconnect. The company continued to monitor the situation and work on restoring full service.
