Microsoft Teams

Microsoft is investigating an ongoing outage preventing customers from sending or receiving messages using the company's Microsoft Teams communication platform.

While Redmond is yet to provide details on what platforms are affected, users report experiencing these issues while using the desktop and mobile Teams apps.

Some have also encountered problems when connecting to the Teams server or the web app starting around 8 AM EST.

"Unsuccessful sending and receiving messages from mobile and desktop applications," someone said on the Downdetector page tracking the incident.

"Large delay in sending and receiving all messages on the desktop app for teams on windows 11 on the east coast," another user added.
