Managing sound and video settings during Teams meetings and calls for optimal communication
Hello Luke, this is Emily.
I'm sorry, but it is not currently possible to move the menu bar from the top of the Teams window to the bottom. The menu bar is a fixed element of the Teams interface and cannot be customized or moved. I will suggest that you use the feedback feature to submit this as a feedback. Click on the Help button on the lower left in Teams, then click on Give Feedback.
