I've got a control that sends e-mail for me using the MAPIMessages and
MAPISession objects. It has to work with addresses that are not necessarily
in the address book of the sender. If the recipient's address is not in the
sender's address book, the user gets an "Unknown Recipient". The user can
click Ok and the e-mail message will come up, but when it is actually sent,
it fails with a "Your message did not reach some of the intended recipients"
message. Please note that this is not a bounce back. Outlook must be
trying again to resolve the name against the address book and when it can't,
it just won't send it. So I located some documentation on how to build an
e-mail address that would pass muster without being in the address book.

Basically the address had to have a format like this:

<Name>[SMTP:<e-mail address>]

With an example being "Bob Smith[SMTP:bob.smith@thisnamedoesnotexist.com]"
(without the quotes, of course).

Unfortunately, this is not working and now I can't find the document that
showed me how to format an address that will pass muster and be sent even if
it does not resolve to an entry in the address book. There must be a way to
do this, since it would be asinine to expect every address that e-mail might
be sent to to also be in the address book. I'm sure it's just a minor thing
to get it working, but I've tried little changes here and there and haven't
hit upon the right format. Does anyone know how to make this work?

Thanks,

Russell Campbell
