Hi, I have a Sub that searches through the Recipient list on a Draft message
to determine if there are any external (outside my company) recipients.
Please see the full code listing below. When I enter a recipient in the To,
CC or BCC box in the draft message, delete that entry, then run this sub the
deleted entry reappears. If I click the Verify Recipients button in the draft
message form prior to running the sub I don't have the problem. So I tried to
simulate the Verify Recipients action in VBA by adding a ResolveAll command
in the beginning of the sub. That doesn't work for some reason. Thanks in
advance for any help you can provide.

' Determine if there are any external email addresses in the
