RPC over HTTP allows your email client to securely connect to and retrieve mail from our hosted Exchange service without needing to establish a VPN. The protocol encapsulates all RPC requests from your Outlook client into an SSL encrypted stream to port 443 (SSL) on our servers. What do I need? You will need to be running Windows XP and Outlook 2003. If you have installed Service Pack 2 (SP2) for XP, you’re ready to go. If not, please visit the Microsoft website and download SP2 (link opens in a new browser window). How to enable RPC over HTTP in Outlook 2003 If you have never installed Outlook on your machine before Step 1 Double click the Outlook 2003 icon on your desktop. Several installation windows will automatically pop up and install Outlook components. When these finish, you will see a blank “Mail” window. Click “Add”. Now proceed to step 2 below.

RPC over HTTP is a feature where Outlook 2003/2007 running on the Windows XP operating system can communicate through the Internet to the IceMAIL Exchange servers without the need for a Virtual Private Network (VPN) connection. Eliminating the VPN connection makes using Outlook 2003/2007 and connecting to IceMAIL much easier.
