cannot access exchange mailboxes via POP3

Hi,

I have an exchange 2003 server which is finally functioning as it should, at least with the Outlook clients.

Now, 2 users need to have POP3 access to their account. And although the POP3 server is running (it's accepting connections at port 110), and those users have pop3 access enabled in the exchange tabs in ADUC, the pop3 connection doesn't work.

when I use telnet to connect and use the standard pop3 commands, it says that the username/password are incorrect. but they are...

what's wrong? Please help!

ciao!

Have you tried to add the domain name, ie.

NetBios-Domain\UserName
or
username@dns-domain

instead of simply using the user name?

Have you allowed within the POP3 Server to use native logon information (default authentification)? If yes, have you setup there a default logon-domain?

well, I already tried to use domain\user

and that gave the same error (-ERR Logon failure: unknown user name or bad password.)

when i try user@domain

I receive the error -ERR Logon failure: user not allowed to log on to this computer.

(although in the ADUC, this user is configured to be able to use pop3, imap, owa, etc etc

okay, I found what caused it!

under NT4, I had already configured users to be able to log on to their own workstation only. Appearently this obstructed them to logon to the server via POP3.... nice nice nice

greetz!

Just an FYI for others that have this issue, if your username doesn't match your exchange alias, you must use netbios-domain\username\alias for the pop3 user.  For example,  MyDomain\dennis\dhwebb would be a pop3 username.
