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 2: Windows Mail will open. Click the Tools menu, then click Accounts.
Step 3: The Internet Accounts window will open. Click Add in the top right corner. Click Mail in the menu that appears. This will open the Internet Connection Wizard.

Note: If it is the first time you have run Windows Mail on this computer, the Internet Connection Setup wizard may start automatically.
Step 4: On the first screen of the Internet Connection Wizard, you'll be asked to enter a display name. This is what most email users will see in the inboxes instead of your email address. Enter your name, then click Next.

Step 5: Enter your full email address. This made up of the mailbox name you chose, an @ symbol and your domain name. Then click Next
