Since yesterday, I am unable to share anything but PPTs in Team meetings with colleagues.

MS Teams 1.2.00.28258 on Mac 10.15 – since yesterday, I cannot share anything but PowerPoint files. The option to share ‘Desktop’ and ‘Windows’ have disappeared. I have checked the boxes in System Preferences > Security > Screen Recording.

hi all,  you have to go deep into preferences and allow the app to access your computer.  I know this isn't the best explanation, but I got it to work on my bosses computer.

This may be it:

  1. Click the Apple menu.
  2. Then, go to System Preferences > Click Security & Privacy > Privacy tab.
  3. Click Screen Recording.
  4. Click the lock icon to make changes.
  5. If required, enter your admin password.
  6. Finally, click the checkbox next to Microsoft Teams.
  7. A notification window will ask you to restart it. Agree.
  8. Then, try again and see if the issue persists.

If not this, something very similar.

You are close to that you have to do, problem is for many that the 'approval' is there but doesn't seem to have any effect. It is as if the program is not paying attention to the approvals.

    I think I found the problem...

    I believe the MS Teams app needs to be able to accept new incoming connections.

    Try adding the exclusion to your OS firewall, and restarting Teams (I'm not sure that a Teams restart is needed).

    Settings -> Security & Privacy -> (unlock) Firewall Options..., then "+" to add the Microsoft Teams and make sure it is set to "Allow incomming connections"

    Hopefully that works for folks...

    FYI, I'm running OSX 10.15.2

    Have tried the Firewall option above (and restarted Teams) but still it doesn't work. Have tested also with Firewall OFF without success.

    Now need to use Skype again to be able to share entire Desktop or Window. On Skype it works without any issues.

    BTW – it works on web version of Teams (Desktop/Window Screenshare).

    FYI, I have macOS Catalina 10.15.2 and the latest version of Teams. Before the OS upgrade it worked perfectly on macOS Mojave.

    Microsoft this is very poor by your usual very good support standards... you introduced a feature breaking change to the Mac Teams client, clearly without QA, then can't even get back to your community about when you plan to resolve it!
