moving sent mail to imap folder

[Kyanam]

Hello,

I have an IMAP account that I moved to Microsoft Office Outlook 2003. I created a rule to move a copy of all mail sent through this account to the sent-mail folder of the imap account. However, the rule does not seem to work. Here is how the rule looks:

===
Apply this rule after I send the message
through the imap_server account
and on this machine only
move a copy to the sent-mail folder
===

Any suggestions? TIA!
