POP3/IMAP4 Exchange 2010 Fetching Issue

I've been banging my head on this one for too long. The skinny of it is that I am unable to get the mailbox to fetch. The SMTP works (or at least doesn't throw an error). I used these settings on another helpdesk software and it works. It states FAILURE: E-mail settings saved successfully. But error occured while trying to check connection with mail server - Problem connecting to mailbox.

I have double checked the credentials and telnet into the server on 143 and on 110. I've attached my support file. I'm running Exchange 2010 SP1 and have both POP3 and IMAP4 services running.

Anything you can do to help would be great!
