The Exchange Server 2007 Client Access server role is responsible for all non-MAPI client communications. This includes:

  • Outlook Web Access (OWA)
  • Outlook Anywhere (RPC-over-HTTPS)
  • Exchange ActiveSync (mobile devices)
  • POP3/IMAP4
  • Exchange Web Services (EWS)

Outlook clients connect directly to the Mailbox server for mailbox and public folder access and do not use the Client Access server, however Outlook 2007 and above clients do connect to the Client Access server for Autodiscover and Autoconfiguration.

This tutorial demonstrates how to install an Exchange Server 2007 Client Access server on Windows Server 2008. It is assumed that you have already extended the Active Directory schema for Exchange 2007.
