You can connect to your mailbox using either the POP3 or IMAP protocols. As a rule of thumb it is better to use POP3 if only one computer accesses your mailbox, while it is better to use IMAP if you have a number of computers that will access your mailbox. Our article Whats the difference between POP and IMAP will explain the differences in more detail.
To set up a different type of mailbox, follow:
Step 1: Open Windows Live Mail. Click Tools , then Accounts in the drop down menu.

Step 2: The Accounts window will open. Click Add in the top right corner.
Step 3: Select E-mail account and click Next.

Step 4: Enter your full email address. This made up of the mailbox name you chose, an @ symbol and your domain name. In the next text box, enter your mailbox password.
Step 5: In the next text box, enter a display name. This is what most email users will see in the inboxes instead of your email address. Select the box marked Manually configure server settings for e-mail account. And click Next.

Step 6: Depending upon your favored connection type, select POP3 or IMAP from the drop down list, and enter the following details.
Incoming Server: Enter mail.yourdomain.co.uk (replacing yourdomain.co.uk with your domain name).
Incoming server port: Should be set at 110 if using POP3, and 143 if using IMAP.
This server requires a secure connection: Leave unchecked.
Log on using: Select Clear text authentication from the drop down menu.
Logon ID: Enter the email address of your mailbox.
Outgoing server: Enter smtp.yourdomain.co.uk (replacing yourdomain.co.uk with your domain name).
Quick Tip: If you are not using Fasthosts nameservers you should enter smtp.livemail.co.uk into this text box.
Outgoing server port: While you can leave the outgoing server port set at 25, many ISP's (BT, AOL, Yahoo etc) will block this port. If you are unable to send email using port 25, you should change it to 587.
This server requires a secure connection: Leave unchecked.
My outgoing server requires authentication: Should be selected.

Step 7: Check the details again, then click Next and Finish to set up your account and close the new account wizard.
