How do you set up outlook express on different accounts on your PC?

I have set up outlook express on one PC account and it works fine. But how do I get it to receive the same emails on different PC accounts without stopping other accounts from receiving the same messages. Is it as simple as signing into the same internet account? Will that allow different accounts to receive the messages? Or do you have to create a shared message store or something?How do you set up outlook express on different accounts on your PC?
You just set up additional Outlook accounts, one for each of your email accounts. (I don't know if you can do that on Outlook Express - you can on Outlook.)
