How to setup Exchange access in Outlook 2003?

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)

1. Click Start, click Control Panel, and then open Add or Remove Programs.
2. Under Currently installed programs, search for the item Windows XP Hotfix (SP2) Q331320.
3. If the item is not present, go to the Microsoft Web site (http://go.microsoft.com/fwlink/?LinkId=18651) and follow the instructions to download and install it.

Verify that the computer is running Outlook 2003 or later

1. Open Outlook.
2. 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

1. 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.
