Help setting up Exchange account in Snow Leopard

[Ipheuria]

I need someone's help, I've got a Macbook Pro and I'm currently running Windows virtually in Fusion. The only real need to run Windows is to have my Exchange account in Outlook. I was excited when I heard that Snow Leopard would support Exchange in Mail because if I could setup my account I would be one step closer to running only Mac OS or not needing to boot Windows as often. I already have two Windows machines at work so it gets quite hectic for me. Anyway I've got Snow Leopard and where I work we have an Exchange 2007 server. So anyone that has successfully setup an exchange account in Mail I need the following information to figure out what I may be doing wrong. You can use examples for some of the info that you can't put for confidentiality reasons. I just need an example of what you've used so I can know the form. ie. Incoming Mail server: IP or URL?

Start Mail
Full Name: Full Name
Email Address: work email address
Password: work email account password
it searches for the email servers for the address...
then goes to the Incoming Mail Server screen
Account Type: Exchange 2007
Incoming Mail server: ??
Username: filled in from previous screen
Password: filled in from previous screen

This is as far as I've gotten because when I type in the URL of our Exchange server which I can reach through any browser it can't connect to the server and says it's unavailable. I need an example of someone who has done it correctly and it works to see what the difference is between their input and my own.

OK figured out the answer for myself. We were entering the external server address. When you're setting up the account it's asking for the internal address. So once I put in the network name of the server everything connected finally. Once it's all setup you can go into preferences and set the external server address so that you can access the email from outside the office through Mail.
