Question : Cannot Access POP3/SMTP through outlook express but Webmail is fine.

For some reason, a user is having problems using pop3/smtp with outlook express.  User is able to login to webmail with no problem, but when trying to access email through outlook express, it keeps saying that it's not the right password.
Here's an example.

webmail.xxxx.com:
Username: Domain\user
password: 1234

Outlook express:
smtp/pop3 set at webmail.xxxx.com
username: Domain\user
password: 1234

With webmail on IE, it works, but with outlook express, it doesn't authenticate.

I'm only having this problem with 2-3 users, but everyone else is fine..
Any suggestions would be greatly appreciated.

Thanks.

Yes, the alias can be changed in Active Directory Users and Computers.  It's on the Exchange General tab.
