Outlook 2003 Not Saving to Sent Items Folder

Outlook 2003 defies intuition. It would make sense that there should be an outbox or a sent items or a "sent" but Microsoft would rather make it really confusing. If you're connecting through imap and you want to have a specific imap folder say "Sent Items" store your sent mail you need to create a rule:

Tools > Rules > New Rule

Don't use the template, start from scratch.

What you want to create is a rule that reads like this:

Apply this rule after I send the message. Uses the message form and on this machine only move a copy to Sent Items folder.
