I am wondering if anyone else has an App Host Tab open up when trying to open new tabs in Outlook. When I try to close these tabs, Outlook resizes, crashes and does all sorts of other strange things. This problem only occurs while using Outlook; it seems to be happening on multiple computers having both Win 10 and 11.
I have done a fresh install of Groupy and tried it on clean installed machines.
Outlook 360 Build 16.0.15629
Windows 10 latest
Windows 11 22H2
