I have no problem like this with Outlook 2003 on XP. Its only since I
upgraded.

Does your SMTP (outgoing mail server) allow attachments that large to be
sent?

It just keeps doing a send and receive but not removing the item from the
Outbox - btw i'm using Vista Business. No error message and it only seems
to happen with large attachments.
