Unable to do any calls with Teams desktop client on macOS (Custom Setup)
DataDavid I am also having this issue. My MacBook Pro updated to the latest version of Catalina yesterday 10.15.5.
Now no one can see or hear me in a Teams call and I cannot see or hear them either although I can see myself.
AdrienneElle Anyone else using ESET Cyber Security? Might be that ESET causes the problem: https://forum.eset.com/topic/23439-microsoft-teams-issues/ They advice to customize the firewall to provide access to Teams Helper. No experience myself so far if it helps.
DataDavid I was just researching this issue because I am unable to do video calls lately too and I came across your reply. I do happen to have ESET installed (an imposition from work). What are the modifications to the firewall required?
J_Gordo Feel free to check the post in the ESET forum (see above). There it says you need to establish a new firewall rule with the following details:
Name: Allow Teams Helper
App: /Applications/Microsoft Teams.app/Contents/Frameworks/Microsoft Teams Helper.app
Action: Allow
Direction: In
Protocol: TCP & UDP
Ports: Remote
Remote Port: All
Destination: Entire internetI have set this rule myself yesterday but I didn't have a chance for a new Teams meeting since then. So I couldn't test the (hopefully positive) effect so far.
