Exchange 2000 uses smtp authentication for sending mail.   You need to
have them modify their 'account' properties on outlook express to
include their username and password for smtp.  They might only have it
for pop3.

It may not fix your problem, but it's a good place to look.

Subject: [exchangelist] Relay problem

Hi everyone.

I have a problem with some Internet freemail accounts.

I have an exchange2000 sp2 setup.

Some of our workers complain that they can't reply to emails that are
sent to their exchange Mailbox. This problem only occurs when the people
use Internet Email, and send the reply or mail from there. If they use
the OWA or the normal MS exhange Server Email, there is no problem. It
also only happens with some adresses not with all. I haven't knowingly
blocked any Email adresses or providers.

The Error message is (translated from Germann)
"the message could not be sent because the recipient was refused by the
server. Server answer: "550 5.7.1 unable to relay for
reby_g@xxxxxxxxxxx", (account: "domainname", SMTP-Server:
"", error number 0x800ccc79).

Can Anyone help me out on this?

Thanks alot
