Microsoft Teams Windows Firewall pop up
Issue : Microsoft Teams client is showing prompt “Windows Firewall has blocked some features of this app” even after adding Windows Firewall Rules. Issue is explained in the article https://docs.microsoft.com/en-us/microsoftteams/get-clients but no resolution.

Teams.exe prompts for windows firewall when making calls. Adding rules to windows firewall requires elevation. Therefore creating a user based installer of software that has features which require elevation is pretty bad is it not?
In our environment Windows firewall is managed by group policy. I have tried creating firewall rules to %USERPROFILE%\AppData\Local\Microsoft\Teams\Current\Teams.exe and also to C:\Users\%USERNAME%\AppData\Local\Microsoft\Teams\Current\Teams.exe. Both of these do not appear to work and the prompt saying C:\Users\joebloggs\AppData\Local\Microsoft\Teams\Current\Teams.exe still pops up.
Can we have an installer that installs the product into the propper directory for installed programs C:\Program Files or C:\Program Files (x86). This way we can create firewall rules in our environment that will work and create a more seamless hassle free environment for our users.
I have also tried following the suggestions at this URL (https://docs.microsoft.com/en-us/microsoftteams/get-clients) and it still prompts for firewall.
The problem is people developing the software aren't taking everything into consideration. This product is going to be used in enterprises then it needs to fit with an enterprise model not a consumer model that it seems to be currently alligned towards.

This issue is now holding up my rollout to over 3000 users. Please advise.

Even adding a firewall roule for %localappdata%\microsoft\teams\current\teams.exe doesn't work. A resolution or at least a workaround would be great. Thanks.
