Thank you SO much for posting this.  I just tried it and (yay!!) it works!

Hey RAL2,

Awesome job for keeping at it and really happy to hear you have a fix now

I'm running Outlook version 2210 (build 15726.20202) and the bug still occurs

That worked!!  Geez!  So it was an Outlook problem and not a Quickbook problem.

Thank you so much!

not resolved yet - MS is telling me to download an outlook.reg file and then restart my machine but it is not working.

FIXED!!!!

I had the same problem and tried all of the suggestions on this thread - Nothing worked.

Then, finally I upgraded from Windows 10 to Windows 11 and my problem went away.
