One of my clients woke to a new search bar in Outlook 2016 right next to the regular search bar, the new search bar is called "App Search", it is bigger than the regular search bar, pushes it aside to the point that it is too small to work with, and the App Search bar itself doesn't work at all, you can click it but nothing happens, I have tried to find a way to remove it but even uninstalling and reinstalling the whole office suite the App Search bar still remains, she has two computers but only one is affected by it.
I would like some help with it, or at least make a notice of it so Microsoft can fix this bug.
