OK - here (assuming Outlook does not trash it, as it usually does) is a
simple test harness I think we can use to discuss your problem.
Can you play with the options and then let us know where the problem

FWIW, in my testing I think there is a bug, but I'm not going to lay
that out until we see what others think, in case I bias the results!
