Provide a feature of main folder Locking in Microsoft Outlook 2016
Some people may have a lot of sub-folders within a folder on the left side column. It would be handy if the main folder could be locked to the underside of the line that separates 'Favorites' with the folders beneath. Why, because when you need to scroll down to the last sub folder for example, you need to scroll all the way back up to be able to close the main folder, thus hiding all the sub folders. So, instead of scrolling, if the main folder heading is locked and doesn't disappear when scrolling it would be much easier to close/hide the main folder/sub folders. Sort of like an excel file, when you can lock the top row so that when you scroll down it does'nt disappear.
