Palm mail will not sync with my IMAP account in Outlook Express

I have an IMAP account set up in Outlook express 6. I try to synchronize my visor platinum but it does not see my IMAP account and so it does not sync anything. I am thinking that because the IMAP accounts in outlook have their own folders, like inbox and sent items it doesn't see that but looks to the local INBOX folder which is empty. How can I make hot sync look to my imap account.
