Configuring POP3 access on Exchange 2013

I’m trying to setup POP3 access on our Exchange 2013 server. As of right now I’ve enabled both the POP3/POP3 backend. Both services are running. I’ve also enabled PlainTextLogin. I’m able to telnet to port 110 of the server, but when I try to login I receive -ERR Logon failure: unknown user name or bad password. I’ve tried restarting both services to no avail.

POP settings are as follows.
