Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
I have just purchased Office365 and coming from Office2000 (which is still great by the way), I also find the Ribbon to take far too much of the space at the top of the screen in Excel and Word. To make a long story short, and avoid pointless discussions, I have also fully understood the the original poster mentioned and simply I think the solution is to remove the Ribbon Section titles to leave just the icons [after all that is what icons are for]. This would reduce the Ribbon height by about 20%, which would at least help. In the old days, Microsoft was the sort of company that continuously looked to optimise its products. This would be an easy right-click in the Ribbon area.
