When I try to send or receive mail, I receive the following message:

There was a problem logging onto your mail server. Your Password was rejected. Account: 'pop3.live.com', Server: 'pop3.live.com', Protocol: POP3, Server Response: '-ERR mailbox for is not available', Port: 995, Secure(SSL): Yes, Server Error: 0x800CCC90, Error Number: 0x800CCC92

Also, a "Logon - pop3.live.com" screen comes up asking me to log on (I am already logged on).

What is going on? Can anyone help?
