It sounds like you don't have an email address set up through Outlook Express.
Outlook Express isn't an email in iteself - it is an email 'client' that allows you to send and receive emails once it has been set up.
If, for example, your ISP provides you with an email, you will need to have (1) your email address (
[email protected]), (2) your password provided by the ISP and (3) your pop3 and smtp addresses. These should be found on your email provider's website (in this case your ISP). They look something like
pop3.yourISP.com and smtp.yourISP.com
or they may both be
mail.yourISP.com
