Hi,

I'm using Visual Basic 6 and I'm trying to read undelivered messages
from a Microsoft Exchange 2000 server.

I have used MAPI, however when I read an undelivered email, I don't
know where I can find the reply code, e.g. 515, 504 etc., in order to
identify why the specific mail couldn't be delivered.

Does anyone knows how can I retrieve the reply codes for undelivered
emails?

Is it possible to access directly the Exchange server without using an
email client, such as Microsoft Outlook, Outlook Express etc., at all?

Thanx

If it's anywhere, it'll be in the bounce message you get back.

Yup, if you're on Exchange 2000, you could use WebDAV, or of course just
use raw SMTP/IMAP/POP3, Otherwise, the MAPIs and CDO1.21 require Outlook
or suchlike.
