Step 1: Install Exchange Server 2007 with Client Access Server Role


Microsoft Exchange Server 2007 has five server roles that you can implement and configure on a server running Microsoft Windows Server 2003. The Client Access Server role is required for mobile messaging deployments and provides access to the following applications and services:

  • Microsoft Outlook Web Access
  • Exchange ActiveSync
  • Post Office Protocol version 3 (POP3)
  • Internet Messaging Application Protocol version 4 (IMAP4)


Exchange ActiveSync is enabled when the Client Access Server role is installed.

The Client Access Server role is added by default during a typical Exchange installation. It may also be installed on a separate server by selecting a custom option. The decision to deploy Exchange Server 2007 on a single server or in a distributed-role architecture depends on the messaging needs and requirements of your organization.


The Client Access Server role should never be installed in the perimeter network unless you are deploying Exchange in a Microsoft Small Business Server deployment. In that configuration, Microsoft recommends that you use a firewall to funnel all Internet traffic that is bound for your Client Access Server. It is also a best practice to run Exchange Best Practice Analyzer before proceeding with your deployment. You can download the Microsoft Exchange Best Practices Analyzer at

The topics presented in these articles include planning and architecture for simple, standard, large, and complex Exchange deployments. The topologies in Network Architecture Alternatives enable both a typical (single server) and a custom (multiple server) installation.


This document describes procedures and guidelines for deploying Windows Mobile 6 with Exchange Server 2007. Exchange Server 2007 roles other than the Client Access Server or Mailbox Server roles are not core components of a mobile messaging system, and are not documented here.
