Setting up email in Microsoft Outlook
This walkthrough shows you how to set up an email account using Outlook 2003. Other versions of Outlook have similar settings, so you can still use this page to help you set up other versions of Outlook.
To get started, select Tools > E-mail Accounts from the menu.
When the wizard appears, choose "Add a new e-mail account" and click Next.
On the next screen, select "POP3" as the server type and click Next. 
The next screen is where we do most of the work. Enter your name and email address under "User Information". Then under "Logon Information" enter your email address again where it asks for the username, and then enter the password we've given you. Under "Server Information" enter "mail.yourdomain.com" as both the incoming and outgoing mail servers. Then click the "More Settings" button.
Choose the "Outgoing Server" tab and tick the box that says "My outgoing server (SMTP) requires authentication". Then choose "Use same settings as my incoming mail server".
Click OK to return to the previous screen. Then click "Next". When the "Congratulations!" screen is display, click "Finish".
To check that everything is set up correctly, try sending yourself an email.
