INTRODUCTION

This article contains information about how to obtain a guide that you can use to help configure the remote procedure call (RPC) over HTTP feature in Microsoft Exchange Server 2003.

Exchange Server 2003 together with Microsoft Office Outlook 2003 and Microsoft Windows Server 2003 support the use of RPC over HTTP to access servers that are running Exchange Server. By using RPC over HTTP, users no longer have to use a virtual private network (VPN) connection to connect to Exchange mailboxes. Users who are running Outlook 2003 on client computers can connect to an Exchange server in a corporate environment from the Internet. The Windows RPC over HTTP feature enables an RPC client such as Outlook 2003 to establish connections across the Internet by tunneling the RPC traffic over HTTP.
