1. Setup Wizard
Start Outlook. Click Tools on the menu bar and select Accounts from the dropdown menu. Click Add and then click Mail. Follow the set-up wizard, filling in your name and the email address that you will be using (for example, username@your-domain.co.uk). This will be visible as the reply address.
2. POP3 Account
The next screen asks which type of incoming mail server to use. Select POP3 and complete the server details with your domain name (same for both).
3. Username
You now need to add a username in order for the server to allow you to send and receive email.
4. Account Name
Finally give your new account a name, select the "Connect using my phone line" radio button and finish the set-up wizard.
You are now ready to use Outlook as your mail client.
