Understanding RPC over HTTP

RPC over HTTP allows remote users to connect to Exchange Server 2003 using the Outlook 2003 MAPI client via the Internet, but without the need for a VPN or other tunneling software, smart cards, or other security tokens. It gives these remote users secure communication access to Outlook features found only in the MAPI client.

Installing and Configuring RPC over HTTP on the Server End

RPC over HTTP requires configuration on the Exchange Server to support HTTP Proxy. Two items must be configured on the server operating as the front-end server for the remote connection:

  • Install RPC over HTTP Windows component

  • Configure IIS to support RPC over HTTP secured communications
