Rather than trying to walk you through every step here, I've located a tutorial for how to set up your email in Outlook. Outlook's email setup is very similar to Outlook Express's setup. The easiest thing to do is to use the email setup wizard under tools/email accounts in OE. Basically, the key things are to make sure that you enter your email address and PW correctly (the PW is case sensitive), then enter the correct settings for your POP and SMTP email servers. The article points out the correct names, but be sure to use the right RR region (like KC.RR.Com if you're in Kansas City).
Make sure you click on the plus sign next to

Good luck and please let me know if this helps!
