This morning, Microsoft Teams suffered an outage with users unable to access Microsoft Teams unless they were using the Teams client. Users trying to navigate to https://teams.microsoft.com were unable to get there with various 500 HTTP errors.
Editor’s Note: This outage lasted about 2 hours including the time to roll out a fix, Exoprise customers knew of the issue around 35 minutes before Microsoft.
Exoprise proactive monitoring first detected the outage in North America starting at 7:20 AM EDT. Our customers were notified by proactive alerts and informed external customers to download the Teams client or switched to alternative meeting methods.

Proactive notification arrives 30 minutes before Office 365 service status.
We will update this page as we detect changes in the infrastructure or have more to update.
