Has anyone here had or know of any issue with Outlook 2016 described below. If I pin the icon to the task bar, when I click on it, it creates a new icon and highlights it for the open Outlook Window. The other windows are stacked under the new icon that shows when I click on the previous one. If I remove the old one and add it again, same problem occurs. If I try add the new icon to the task bar, it goes to a blank icon after I shut all instances of Outlook 2016. I have stacking set to on and all windows stack under the new icon created and it's only with Outlook that this occurs. Every time I click on the original icon, it opens a new Outlook window under the new stack. If I click on the original, it simply opens outlook. Very weird.
