What you need to know

  • Reports of Microsoft Teams outages started spiking today at 6:41 AM EST.
  • The outage map indicates that many of the outages have occurred on the East Coast of the United States.
  • Many people haven't started work yet, so it's difficult to determine how widespread the issues are.

Microsoft Teams outage reports started spiking at 6:41 AM EST, according to Downdetector. The outage map on Downdetector indicates that Teams isn't working for many people on the East Coast of the United States.

Many people struggling to use Teams see a message stating, "Operation failed with unexpected error." As of 6:55 AM EST, reports spiked for outages from zero to 355, but they are rising quickly. Teams has millions of users, so 355 reports isn't a dramatically high number, but the rate of change indicates an issue.

The Microsoft 365 Status Twitter account confirmed that outages affected Europe and Asia as they first began to be reported. A later Tweet confirmed that the issues affect Teams users around the world. Microsoft is reviewing the issue.

Since the workday hasn't started for many people in the United States, it's difficult to determine if the outages are regionalized or only being reported as people try to sign on for work. We'll continue to update this post as more information becomes available.
