POP3 Users won't successfully authenticate on Exchange Server 2003.
Posted on 2006-06-20
I recently setup POP3 functionality for my Exchange Server 2003, and I can connect without a problem, but when I do connect, regardless of the user trying to connect, it won't successfully authenticate. For the username, I've tried it just 'user' as well as 'firstname.lastname@example.org' -- but neither works. I've also tried with other users and none of them want to authenticate. It does pull up the 'Enter Network Password' window, in which the first blank is the address of my mail server, the second blank is the 'User' and the third is the 'Password'. I have not set it to save password, because I wanted to successfully connect before I saved it. When I test it from within the domain, using the SMTP it works fine with user/pass. Have no idea as to why it won't take any user/pass via pop3... Please help..
