Thank you, @WesterFence Wester,

This is exactly my issue.  I even enlisted our IT company's help a couple of months ago to try and resolve this issue and they couldn't sort it out either, so I'm stuck using the old Outlook until QBD makes some compatibility improvements.

When they made tweaks and I tried using the new version it would trigger something in QBD and it would shut Outlook down and revert back to the old version.  I have no other issues with other programs interfacing with any version of Outlook which leads me to believe this is definitely an unresolved QBD problem.
