Prerequisites for RPC over HTTP with Exchange Server 2003

Exchange Server 2003 with the RPC over HTTP Windows component is required on RPC proxy Exchange Servers.

Client computers require Outlook 2003 with one of the following versions of Windows:

Windows XP Service Pack 2 or later
Windows Vista

Outlook Add-Ins (any type) are required on desktop computers.

You can configure RPC over HTTP access to Enterprise Vault after you have set up your Enterprise Vault server for Exchange Server archiving and distributed Enterprise Vault Add-Ins to desktop computers.

You then install and configure Enterprise Vault OWA Extensions on RPC proxy servers and target Exchange Servers. For this reason, the additional prerequisites listed for Enterprise Vault OWA 2003 Extensions are also needed if you are configuring RPC over HTTP access with Exchange Server 2003.

See the Setting up Exchange Server Archiving manual for instructions on setting up RPC over HTTP access to Enterprise Vault.

The instructions given assume that you have already configured RPC over HTTP on RPC proxy servers and target Exchange Servers. Users' computers must also be set up to use RPC over HTTP access to the Exchange Server.
