Hi, Mary

If you used the account set-up wizard in MS outlook 3 you will notice a test button after putting in the required information like: Your name, e-mail address, pop3 and smtp etc. You can then test the connection by pressing the test connection button. If there is a problem it will pop up in a seperate box. If you are not sure of your pop3 or smtp info you can look under tools in the express version, then click on accounts, pick the account that you know was able to connect and use that information to put in your outlook version. Also make sure that the correct account is selected as you default user account. If you can not find or the information in express is incorrect just contact your isp provider they will assist you in setting the account up.

Hope this helped,
Have a great day.
