In MS Teams , I cannot share my Desktop / Application Windows. Teams alerts me that it needs Screen Recording permissions, although I have actually granted these before, and the regarding boxes in System Preferences are already ticked. 

I have the newest version of Catalina and Teams. Nevertheless I don´t know exactly which applications are blocking the Teams screen sharing and why., I have followed all suggestions such as using the online version, same issue occurs, removing VPNs and rebooting and updating apps and the mac itself......I use Teams constantly for work and this is causing me a major hassle!

Thanks

    My daughter has a MacBook Air, brand new.  We bought it for eLearing.  She's logging on to Teams and she can see the presenter, and the presenter can see her, but she can't see any other of her classmates.  We have tried the web app and desktop app.  In both versions she cannot see her classmates.  This is so frustrating.

    I experienced the same problem while teaching one of my courses online. The easiest fix is to download MacOS 11.0.1 Big Sur. This upgrade solved my problem.

    If you are using an older MacOS open Preferences  >  Privacy and Security > Display > ensure MS Teams is checked. DO NOT CLOSE the preferences window, leave it open on your screen. I was able to screen share as usual. 

    Oh interesting - I did not realize there was a new OS.  Will try that!  Someone else also mentioned leaving the preferences window open, so will look into that too.  Thanks!

    I had the same issue and this is what I did to work around it.  

    I turned off my firewall and also did the following actions on my Mac. 

    Go into System Preferences and do the following steps: 

    System Preferences > Sharing > Service: Screen Sharing, check the box to the left of Screen Sharing. 

    Make sure to verify which users can share their screen.  

    If you will be sharing files make sure to check the box next to > Service: File Share.  

    Also select Options and check Share file sand folders SMB and select the account on the Mac which will be sharing the file (you will need to enter the password for the user to allow this action). 

    Hopefully this helps with Mac users and utilization of Microsoft Teams.

    Thank you thank you thank you!  Was getting ready to go into beast mode with my Mac for not being able to screen share.  Going into system preferences and checking the box for MS Teams on Screen Recording fixed the inability to share a screen or doc, etc.  Appreciate the tip.
