Hi, 

Even if it is not recommended to use proxies for Teams traffic and if you anyway decides to use proxy you should reconsider that a couple if times. If you after reconsideration anyway decides to let Teams traffic go thru the proxy you should know that it probably will end up with problems, and think about it a couple of times extra.

 

So, nobody recommends Teams traffic to go thru a proxy. But the PTR records should be added, so that might help you a bit. Maybe ThereseSolimeno can get this to the correct people?

52.114.188.1      PTR doesn't exist

52.114.188.254  PTR doesn't exist

52.114.189.1      PTR doesn't exist

52.114.189.254  PTR doesn't exist

52.114.190.1      PTR doesn't exist

52.114.190.254  PTR doesn't exist

52.114.191.1      PTR doesn't exist

52.114.191.254  PTR doesn't exist

ThereseSolimeno I see that an answer has been marked, does it mean you were able to get this to the right team?

        I talked to people in the product group yesterday about this so now they are aware. No ETA when it can be solved but I keep you updated when I hear anything.
