Question about Outlook Express

Split from this thread.

I can send and receive emails from my Windows Live Mail Account when i am home but if I go away from home I can still receive emails but can't send them. they get stuck in my outbox. I have had this problem since I got this computer with the Windows Live Mail Account. I don't have a hotmail account, does that matter?

An incorrect password was entered. The next time you send or receive messages, you'll be asked to enter your user name and password for this account.

Server Error: 0x800CCC90

Server Response: -ERR [SYS/TEMP] internal server error (#IS6532)

Server: 'inbound.att.net'

Windows Live Mail Error ID: 0x800CCC92

Protocol: POP3

Port: 995

Secure(SSL): Yes

I don't have to enter a password I just click on my email.

After a I enter my password the messages come over.  But later on I click on my email and I get the same thing.

Help!
