Exchange Server 2003 and POP3 or IMAP

We currently have Exchange Server 2003 running on Windows Server 2003..
All clients use Microsoft Outlook 2003 and are connected using Microsoft Exchange Server.
All clients will only ever read/send email from within our domain, which is all controlled using Active Directory. Everything in this setup is working perfectly and as we want it to. No users will want, or need to see any changes to how they use Outlook.

We have a new project that requires that I code a program that can read a specific email box and save any attachments from emails that are in that box, delete the email and then do some database stuff.
This process will only be running from within our network on a machine in the server room.  It will query that email box every 5 mins looking for mail and doing its thing.

So basically, I need to enable POP3 for a single email address.  In the future, we may need to add a few more here and there, but these will be onses and twoses, not for mass use or anyone else to know about.

I download the trial version of MailBee.Net Objects.  I am using .NET 3.5 on VS 2008.

I cannot, for the life of me, figure out how to connect to the Exchange Server to read mail.

I was able to modify he code to read email from my home POP3 account, so I know that MailBee.Net works.

I can modify the code so that I can send an email out from Exchange Server (SMTP) and that works fine too.

I think I have narrowed it down to POP3 not being enabled on the server.
When I telnet companymail 110 it fails.
If I telnet companymail 25 it works (or at least I can connect)

MailBee.Net can use POP3 or IMAP, but I was just going with POP3 since that i what I have normally used for anything email related.

How do I go about enabling POP3 (or IMAP) for this Exchange Server so that it effect any of the other users?  I dont want to have to use any new domains or anything, just a simple "click here" and then I can access the email address using POP3 or IMAP

Thanks!!!
Rico

You need to change the Microsoft Exchange POP3 service (start, run, services.msc - press enter) from disabled to automatic, then start the service.
Once started, make sure that the POP3 Virtual Server is started - use Exchange System Manager, expand Servers, Expand Protocols, Expand POP3.  Seelct the default POP3 virtual server, then right-click on it and choose start.  If Start is not available, then it is already running.
IMAP is exactly the same, just start the IMAP service.

You can start both services happily without any effect on the user.
If you want to access the server via POP3 or IMAP outside of the company, you will have to open up ports TCP 110 (POP3) and TCP 143 (IMAP) on the firewall and port forward those ports to the server.
