This what i DID:... Do I'm missing something.  Please let me know.

Thank you Expert!

Using Outlook via the Internet
If you are using Microsoft® Office Outlook® 2003, you can connect to the computer running Windows® Small Business Server through the Internet using the feature called RPC over HTTP. This means you can remotely access your server e-mail account from the Internet when you are working outside your organization's firewall. You do not need security-related hardware or software (such as smart cards or security tokens), and you do not have to establish a virtual private network (VPN) connection to the server.
Comparing RPC over HTTP and Outlook Web Access
When using RPC over HTTP to access your mailbox, you get the full functionality of Outlook 2003. For example, you can work offline, use Microsoft Office Word 2003 as your e-mail editor, and easily organize your mailbox.
To use Outlook via the Internet
Ensure that the following requirements have been met on the client computer:
Verify that the computer is running Microsoft Windows XP Service Pack 1 or later
Click Start, right-click My Computer, and then click Properties.
The version of the operating system and service pack is displayed under System. If you do not see a service pack version, there is no service pack installed.
Verify that Windows update Q331320 is installed on the computer (not required if you are running Windows XP Service Pack 2 or later)
Click Start, click Control Panel, and then open Add or Remove Programs.
Under Currently installed programs, search for the item Windows XP Hotfix (SP2) Q331320.
If the item is not present, go to the Microsoft Web site ( and follow the instructions to download and install it.
Verify that the computer is running Outlook 2003 or later
Open Outlook.
Click the Help menu, and then click About Microsoft Office Outlook. The version number appears at the top of the box.
Verify that the computer trusts the certificate used by the server
Open Internet Explorer, and then in the address bar type:
If the certificate is trusted, a certificate warning does not appear. In this case, continue with step 1 under Ensure that you have an Outlook profile configured for the server.
If the certificate is not trusted, a warning appears. Click View Certificate, click Install Certificate, and then follow the instructions.
Ensure that you have an Outlook profile configured for the server

If your profile does not appear, open Outlook and follow the instructions to create a profile before proceeding.
If Microsoft Exchange Server does not appear in the list, the existing profile is not associated with a Microsoft Exchange Server e-mail account. Click Cancel, and then click Close. Continue with step 3 to add a profile.
If there is an existing Microsoft Exchange Server profile, continue with step 3 under Configure the computer for RPC over HTTP.
Click Add. The New Profile dialog box appears.

I would bet that the required ports to make this work are not open in your company's firewall.
You can use windows Dial up VPN, if your work is set up for you to use that (pptp protocol), all you have to do is establish a VPN connection between your machine and server, after that it will work.

SBS 2003 comes with an options of RPC-http, you can basiclly connect to your exchange without any more VPN dial up, but that needs further configuration, dunno whether your sys admin set it up already.
