Is Outlook down? Widespread outage hits Microsoft email and other apps

A widespread outage has hit Microsoft platforms, including Outlook, email, Teams, Copilot, and other services within the Microsoft 365 suite, on Thursday. Nearly 130,000 users on Downdetector reported problems accessing Outlook just after 1 p.m. ET, with many users unable to send or receive emails, or having difficulty loading their inboxes.

Microsoft acknowledged the disruptions, particularly related to its email and Teams applications, and stated that a portion of its infrastructure was experiencing elevated load, likely contributing to the connectivity errors. The company determined that a number of servers were unexpectedly unavailable due to a problem causing them to fail during automated health checks.

Microsoft is testing a fix and rolling out an alternative method to bring impacted servers back online, and is aggressively pursuing all pathways to reduce the impact of the outage.
