Hi all. I'm trying to create a separate e-mail account on windows mail for buisiness use, but must be doing something wrong

This is what I tried:
Click tools - accounts - add
Then I get 'your name' "type your name as you would like it to appear and it shows my current user
name@talktalk.netI assume I change this to my new user account
name@talktalk.netIt then asks for an e-mail address - is this the same as above? Account
name@talktalk.net?
Then incoming mail server (pop3 or imap) mine's pop3 so I type pop3.talktalk.net
Outgoing server name - smtp.talktalk.net
It then shows my chosen user name and asks for a password
I type the password and it says congratulations, you have successfully entered all the information required to set up your account, but when I send a test e-mail I get nothing...
Any ideas..?
Regards, confused...
