Please go to Tools menu in Microsoft Outlook and then select E-mail Accounts.
This will bring up new Wizard window. And please select Add a new e-mail account option from the wizard, and then click Next.
In the next screen, please choose your server type, either select POP3 or IMAP, and then click Next.
On the Internet E-mail Settings (POP3/IMAP) window, enter the information that you have obtained from your administrator (Refer from table above). Check on the box next to Remember password so that you don’t have to enter it every time you send/receive email.
Click on the More Settings… button. This will open the Internet E-mail Settings window. On the Internet E-mail Settings window, go to the Outgoing Server tab.
Check the option My outgoing server (SMTP) requires authentication and make sure to choose Use same settings as my incoming mail server below.
Go to the Advanced tab, and then change the Incoming server (POP3) to 110, and the Outgoing server (SMTP) port to 25. Specifically for SMTP port, Some ISPs block the outgoing mail server port (25). Please change this port number to 26.
The window will be closed and you will return back to the Internet E-mail Settings window. You can always click Test Account Settings … to test the email account setting.
Now you can send and receive your domain email account right from your PC/laptop.
