That's embarrassing.  I thought I looked carefully and now I see the ports.  Thank you (for not making fun of me)!

I'll add that I've added these rules, and Teams seems to be functioning properly now.

Where did you get those ports and IPs?

Theoretically creating an application-agnostic rule should work.

Ya, but I don't think anyone has done the work to figure out what ports Teams uses.  Also, it might be that malware traverses those ports too.  Or, Microsoft adds a port without telling anyone.

I have a ticket with Microsoft and they are refusing tell me what ports and protocols their app uses.

Would just whitelisting /Applications/Microsoft Teams.app also allow all of the sub folders? 

 

/Applications/Microsoft Teams.app/Contents/Frameworks/Microsoft Teams Helper (Renderer).app/Contents/MacOS/Microsoft Teams Helper (Renderer)

Definitely not.  I tested this thoroughly.

No worries, trying to figure out if there is a way to whitelist a higher level of the directory so that if MS make more changes, then it won't be impacted.

Any input @Marcos

Yes, I'm wondering about the same.  I tried to put /Applications/Microsoft Teams.app/*, but I guess it doesn't like *s.

Based on some early reports, this might be working!

Thank you so much!

They added a new app pathway in the latest update and it also needs allowed on the firewall, it is (Renderer)

/Applications/Microsoft Teams.app/Contents/Frameworks/Microsoft Teams Helper (Renderer).app/Contents/MacOS/Microsoft Teams Helper (Renderer)

 

Thank you so much!  I'll try this immediately and report back!

I just had a reply from Eset tech support and they suggested adding rules for the following, I already had the first two so hopefully the third rule will be what resolves for me. I don't have the systems available to me right now to test.

/Applications/Microsoft Teams.app
/Applications/Microsoft Teams.app/Contents/Frameworks/Microsoft Teams Helper.app
/Applications/Microsoft Teams.app/Contents/Frameworks/Microsoft Teams Helper.app/Contents/MacOS/Microsoft Teams Helper
 

This does not work.  Users are still have constant dropped Teams calls.  With the Firewall completely off, it's perfect.
