It is highly unlikely that a user would have their Inbox set up to accept items only of certain message classes. Maybe the mailbox is just full? I'd suggest you ask about this on the microsoft.public.exchange.clients forum.

Some of my organizational forms are being rejected by the users mailbox after
they are sent.

Error: The message reached the recipient's e-mail system, but delivery was
refused. Attempt to resend the message. If it still fails, contact your
system administrator.


Can anyone help me figure out what is going on?

thank you.
