Outlook Express downloaded to mail.app?

Is it possible to have my outlook express (work emails) be on the mail.app server so that I can get them immediately on my application bar rather than having to check it every so often? I did a search but could only find info about transferring emails.

TIA!

I am a little puzzled about what you want exactly? You could just create a forwarding address to your mac email address for your work emails

I'm sorry, I reread it and it is unclear.

I have an aol address, and those emails are accessed through the Mail app (not Mac mail). However, when I tried to set it up to get my mail through Outlook Express, it would not work. So I am wondering if I can get my Outlook Express emails through the Mail application on my Mac?
