Teams Screen Sharing Disabled

I had this same issue with a few users in our corporation.

I was able to see that the user could ONLY screen share during an incoming call or just by screen sharing directly instead. I checked to see if I could sign them into my Teams app installed on my laptop and the issue was no longer present. I also checked the web version of Teams and the issue was not present either. Below was the following issue on their own laptop and their install of Teams:

After trying to delete cache, edit the registry, uninstall/reinstall the Teams program, reboot the machine, etc. I was able to do the following to get it working which didn't make sense since the cache was being physically deleted in the AppData folder:

1. I signed the user out of Microsoft Teams and signed into my account. The issue was removed.

2. I signed back into the user's account and the issue was no longer present.

3. With another user I just signed them out and back in and the issue was removed.

During the 2nd step, I did receive the following message after trying to sign them back in:

When clicking on "try again" the program closed out and reopened. The user was able to screen share after that with no issues when initiating the call.
