Additional features, settings, or issues not covered by specific Microsoft Teams categories
Hello,
Here is the solution:
1. Click somewhere in the "You're Sharing" Bar (I prefer somewhere in the background to avoid clicking a button, but anywhere works)
2. Press CTRL+W
The bar should disappear/close. This way, you don't have to restructure your browser or display layouts, and you do not have to share a window; you can still share your full screen.
Do make sure that you have selected / are active in that "You're Sharing" bar's window, as it will close whichever window you are currently using. So if you miss the bar, you risk closing the Teams meeting window.
** NOTE: This closes the bar only for that instance. If you stop sharing and then re-share your screen, or start sharing in a different meeting, you will have to repeat the process every time **
I hope this helps! I spent a week trying to figure this out, and after a team discussion, one of my team members (somehow) found this solution, so I cannot take credit. I just remember seeing many others frustrated with the same issue I had, so I figured I would come back and share!
All the best.
