The Quick Access Toolbar is a customizable toolbar containing a set of commands that are independent of the tab that is currently displayed.
The Quick Access Toolbar can be located in one of two places:
Upper-left corner next to the Microsoft Office Button (default location)
Below the Ribbon, which is part of the Microsoft Office Fluent user interface
If you don't want the Quick Access Toolbar to be displayed in its current location, you can move it to the other location. If you find that the default location next to the Microsoft Office Button is too far from your work area to be convenient, you may want to move it closer to your work area. The location below the Ribbon encroaches on the work area. Therefore, if you want to maximize the work area, you may want to keep the Quick Access Toolbar in its default location.
