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.
Quick Tip: Before you start you should ask your Internet service provider for their "SMTP Server Settings" to use for this mailbox.
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 how you would like to connect, ensure that POP3 or IMAP is selected 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 required 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.
In the Outgoing server Information section you should enter the SMTP settings as advised by your Internet Service Provider.

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