Using Classic Outlook on Windows for personal email, calendar, and contact management
After messing around with every solution in this page, I finally got mine to act correctly.
I used zx3junglist answer in a different way. I found a regedit entry for:
Computer\HKEY_CLASSES_ROOT\AppUserModelId\Microsoft.Office.OUTLOOK.EXE.15
But I am using Outlook 2016 (should be OUTLOOK.EXE.16, not 15)
I renamed Computer\HKEY_CLASSES_ROOT\AppUserModelId\Microsoft.Office.OUTLOOK.EXE.15
to
Computer\HKEY_CLASSES_ROOT\AppUserModelId\Microsoft.Office.OUTLOOK.EXE.16
and popups work. When I click the popup, I get the email!
I hope this helps some!
wow....
I'm going to wait to test it a bit more before I celebrate, but that just might have solved my issue FINALLY!
its too simple to be true.... stay tuned

After a week of testing, I can confidently confirm: workaround is working!
@davekittredge and @zx3junglist, outstanding result. Thank you.
