Microsoft Teams outage causes connection issues, message delays

Microsoft is investigating an ongoing and widespread outage impacting the users of its Teams communication platform and causing connectivity issues, login problems, and message delays.

While Redmond is still working on addressing these ongoing problems, it revealed that a networking issue might be the root cause of this outage.

"We've identified a networking issue impacting a portion of the Teams service and we're performing a failover to remediate impact. Additional information can be found under TM710344 in the admin center," tweeted the official Microsoft account for updates on Microsoft365 service incidents.

Affected customers have reported login and server connection issues, desktop and mobile Teams apps freezing on the loading screen, and message delivery problems.

Other reports mention chat history not being available and images no longer displaying in chat, as well as being left in the waiting room after joining Teams meetings.

On impacted systems, customers see "We've run into a server error. Some functions might not work right now but you can continue to use the app" errors.

According to the TM710344 incident report in the Microsoft 365 admin center, the outage was first acknowledged by Redmond at 10:37 AM EST and it impacts customers across North America, Europe, the Middle East, and Africa regions.

The outage affects users performing a cold boot, who may not be able to log into teams and will see an "oops" page. It also causes users attempting to log into their accounts and unlocking devices to see missing messages.

"Our review of service telemetry indicates a portion of database infrastructure that facilitates multiple APls is experiencing a networking issue, resulting in impact," Microsoft said.

"We're continuing our investigation to isolate the underlying cause of the networking issue and develop remediation actions."
