I have an application that uses MAPI to send an email message. This message
is simple, with one recipient, a subject, message, and attachments. Going
through Outlook Express, it works beautifully. In Outlook however, it is
added to my Outbox, but the message when sent is returned undeliverable.
When looking at the Sent Item, I can see that there is no "From" address. I
am trying to use the SignOn Method. Whether I include the Username Propery
and Password Property, Outlook Express ignores them, but they seem to make no
different to Outlook. Any suggestions on why the "From" name/address will
not show up or how I need to log on in order to get them to show up in
Outlook? I do not have Exchange Server - Outlook is being used as part of
Office 2003.
