Microphone not working on Skype for business

This appears to be a known feature of 16.28.175. Microsoft recommends some twisted operations on the TCC.db :(

The better solution appears to be to download 16.28.142 from https://download.microsoft.com/download/D/0/5/D055DA17-C7B8-4257-89A1-78E7BBE3833F/SkypeForBusinessInstaller-16.28.0.120.pkg. Just install over the newer version. As soon as you make a phone call SfB will properly ask for the permissions to access the microphone and life is good again.

Thanks much for suggesting this solution: it solved my problem (video yes but SFB would not allow for mic access). I pre-emptively removed 16.28.175 first before I installed 16.28.120. Today's telecon - FINALLY! - went off without a hitch.

Hello!

Please check out the following link to ensure your settings on your Mac are set properly.

Let me know if this helps or if you need further assistance!

This issue could be that Microsoft no longer support specifically "Skype for Business" as it is now a consumer product. As such the specific "Skype for business" application might not be getting any further updates. The "business" application from Microsoft is now MS Teams.

I would recommend you try downloading the main Skype application and installing it and seeing if this solves the issue.

Let me know if this works!

Thanks. Off all the many tips I read, this is the first one that solves the problem for me.

I had to remove 16.28.175 first before it installed 16.28.120.
