If your Microsoft Teams work chat went quiet this Friday, chances are your boss didn’t let you out early for the weekend.

The workspace chat and videoconferencing service started experiencing issues in various regions of the world earlier in the day, with the outage ultimately lasting for hours before slowly returning to normal.

Over 2,500 incidents with Microsoft Teams were logged on outage tracking website at the peak of the outage close to 2 p.m. Eastern. Microsoft acknowledged the outage on X, formerly known as Twitter, at 11:45 a.m. Eastern.

Downdetector is a service that tracks outages by collecting status reports from several sources, including user-submitted errors on its platform.

By 8 p.m. Eastern, the service was logging around 20 reports of service issues.

Microsoft said in a post on X that it had identified a “networking issue impacting a portion of the Teams Service,” though it’s not exactly clear what caused the issue.
