outlook express problem

hi!!
i’m using outlook express 5 from my workplace to access and organize my mail accounts. i’ve set up my companys account as well as yahoo’s account both of which happen to be pop3..so whenever i receive any mails on either of these accounts..it goes to the default inbox folder of outlook….
in case of another IMAP account i could make a new folder and all the mails get downloaded there. How do i achieve this for the first two pop accounts.
Any help will be greatly appreciated.

regards
mayuresh
