I have a problem with some POP3 users:
- The error is unknown user name or bad password.
- their accounts are enabled.
- tried to reset the passwords.
- they can loging to OWA with no problem.
- I have a POP3 frontend and the mail boxes on backend and these users can
loging (by telnet) on the backend.
it is appear that it is POP problem, I restarted a POP machine but still
have same problem....
