    Hi,

     

    Do you get this for one computer or all computers in one location?

     

    First you can start with testing with Network Testing Companion, read more about it here:

    If your are using a proxy, bypass that for Teams traffic.

     

    Firewall ports 80 and 443 and UDP ports 3478 through 3481 from the clients to the internet have to be open to get an good experience.
