My computer is Windows 7 64 bit

I keep getting a message that the wrong password has been entered with the Server error 0x800CCC90 and Windows Live Mail Error 0x800CCC92.

I have removed and reset the email address several times, changed the password several times but with the same message after each attempt.

I know that all the details of the set up are correct and I have successfully installed three email addresses in Windows Live Mail.                                         

 I have received emails successfully to each of these addresses but I am unable to send replies. The error message reads as follows;

Server Error  0x800CCC90

Server Response - Err Login failed

Server mail.plus.net

Windows Live Mail Error  0x800CCC92

Protocol POP3

Port 110

Secure(SSU) No

Can anyone sort this for me?
