Exchange 2007 POP3 Settings

I am trying to connect to our Exchange Server 2007(Not SP1) via POP from our SupportTrio system (an online website for users to submit their support tickets. Support tickets are emailed to a "Support" user on our Exchange Server. This SupportTrio is supposed to login to our Exchane Server via POP3 to retrieve these email). I am getting an error message, saying SupportTrio cannot connect to our POP3 acct.

I contacted support and this is what they wrote:
It appears that this POP account uses an unsupported method of authentication. We support the following methods of authentication: APOP, PLAIN, USER, LOGIN, CRAM-MD5, and DIGEST-MD5.

Into which mode, do I have to set our Exchange Server 2007 POP3 to be able to support their authentication methods?

The following documents from Microsoft explain how to make changes to pop3 security in exchange.

It looks like from the email that you received back that you need to use a plain text authentication for the pop 3

I tried switching to plain text authentication. Exchange switched over successfully, but I am still getting an error message that I posted below. Is there a log somewhere on Exchange Server for POP to see if there is even any communication going on at all between my web host and my internal exchange server?

Below is the solution that ended up working:

Changed POP3 authentication to PlainTextAuthentication, but it still didn't work on port 110. Checked that all usernames and passwords were correct. Then found out that GoDaddy Shared Hosting is blocking communication on port 110 and 995. Had to go with a dedicated server where port 110 and 995 was open.

Solution:
POP Server: ssl://mail.domain.com or ssl://xx.xx.xx.xx <--- public ip address of exchange server
Port: 995
