This document is designed primarily for Information Technology (IT) professionals who are responsible for planning and deploying mobile messaging systems that use Microsoft Exchange Server 2003 with Service Pack 2 (SP2) and Windows Mobile–based devices that have the Messaging and Security Feature Pack (MSFP). Document StructureThis document is divided into two main sections that include the following: | • | The essential elements of a mobile messaging system, including system requirements; a summary of deployment procedures; an overview of the features of the Messaging and Security Feature Pack; an introduction to direct push technology; a summary of ISA Server 2006 features; and best practices for networking, security, and device management. | | • | The guidelines and resources for the deployment of a mobile messaging system, including updating Exchange Server 2003 SP2, setting up Microsoft Exchange ActiveSync for mobile access, creating a protected communications environment, setting up an ISA Server 2006 environment, and procedures for setting up and managing mobile devices. |
For current information about deploying mobile messaging solutions and managing Windows Mobile–based devices, visit the Windows Mobile Center Web site. AssumptionsThis document assumes that you have an understanding of Microsoft Office Outlook® Web Access, Exchange ActiveSync, Hypertext Transfer Protocol (HTTP), basic Exchange Server 2003 concepts, and basic Microsoft Windows Internet Information Services (IIS) concepts. Software RequirementsThe following table presents the operating systems and applications that are required for the recommended deployment. |
Exchange front-end server | | • | Microsoft Exchange Server 2003 SP2 | | • | Microsoft Windows Server 2003 with Service Pack 1 (SP1), or Microsoft Windows 2000 Server with Service Pack 4 (SP4) |
| Additional Exchange server(s) | | • | Microsoft Exchange Server 2003 or later | | • | Microsoft Windows Server 2003 with Service Pack 1 (SP1), or Microsoft Windows 2000 Server with Service Pack 4 (SP4) |
| LDAP Server | | • | Windows Server 2003 or Windows 2000 Server |
| Exchange server where Exchange ActiveSync Mobile Administration Web tool is installed | | • | Microsoft Exchange Server 2003 SP2 | | • | Microsoft Windows Server 2003 with Service Pack 1 (SP1) | | • | Internet Information Services (IIS) 6.0 |
| Mobile devices | | • | Windows Mobile 5.0–based devices that have the Messaging and Security Feature Pack |
|
 Note Windows Mobile 5.0–based devices that have a version number of 148xx.2.x.x or later include the Messaging and Security Feature Pack. To find the operating system version on the device, select Start, choose Settings, and then select About. Optional ItemsYou can implement the following components for security and device management tools. See Network Architecture Alternatives in this document. | • | Microsoft Desktop ActiveSync 4.1 or later, which can be downloaded from the Microsoft download Web site. | | • | Microsoft Internet Security and Acceleration (ISA) Server 2006 (or ISA Server 2004 or third party firewall) | | • | Windows Certification Authority (CA) | | • | RSA Authentication Manager 6.0 from RSA Security | | • | RSA Authentication Agent for Microsoft Windows from RSA Security | | • | RSA SecurID Authenticator from RSA Security |
Deployment Process SummaryBecause corporate network configurations and security policies vary, the deployment process will vary for each mobile messaging system installation. This deployment process includes the required steps and the recommended steps for deploying a mobile messaging solution that uses Exchange Server 2003 SP2 and Windows Mobile 5.0–based devices. Note The following steps outline the process for setting up a mobile messaging solution with ISA Server 2006 in a workgroup in a perimeter network, with LDAP authentication. For more information on alternative network configurations, see Network Architecture Alternatives in this document. The process can be accomplished in the following eight steps: | • | Step 1: Upgrade Front-End Server to Exchange Server 2003 SP2 | | • | Step 2: Update All Servers with Security Patches | | • | Step 3: Protect Communications with Mobile Devices | | • | Step 4: Protect Communications Between the Exchange Server and Other Servers | | • | Step 5: Install and Configure ISA Server 2006 or Other Firewall | | • | Step 6: Configure Mobile Device Access on the Exchange Server | | • | Step 7: Install the Exchange ActiveSync Mobile Administration Web Tool | | • | Step 8: Manage and Configure Mobile Devices |
