Implementing and Maintaining E-Mail Clients to Support Message Security in Exchange 2003


Topic Last Modified: 2005-05-19

Chapter 2, "Understanding How Microsoft Exchange 2003 Supports Message Security," provided an overview of the components that make up a Microsoft® Exchange Server 2003-based message security system: Exchange Server 2003, the e-mail client, and public key infrastructure (PKI). Chapter 3, "Implementing and Maintaining Exchange 2003 to Support Message Security," provided Exchange administrators with the information to implement the Exchange 2003 portion of a Secure/Multipurpose Internet Mail Extensions (S/MIME)-based message security system.

This chapter provides information to help the e-mail client administrator implement an e-mail client in an S/MIME-based message security system that uses Exchange 2003. This chapter supplements documentation for specific e-mail clients.

This chapter is intended primarily for e-mail client administrators. In addition, Exchange administrators should review this chapter to familiarize themselves with issues that are specific to different e-mail clients.

This chapter provides information about implementing and maintaining the following e-mail clients in an Exchange 2003-based S/MIME message security system:

  • Microsoft Outlook® MAPI-based clients

  • Internet standards Post Office Protocol version 3 (POP3) and Internet Message Access Protocol version 4rev1 (IMAP4) clients

  • Outlook Web Access clients (without the S/MIME control)

    This chapter does not discuss Outlook Web Access with the S/MIME control. For more information about Outlook Web Access with the S/MIME control, see Implementing and Maintaining the Outlook Web Access S/MIME Control.
  • Outlook Mobile Access clients

  • Exchange ActiveSync® clients

This section presumes that you have read Understanding Message Security and Understanding How Exchange 2003 Supports Message Security, or you have an equivalent understanding of the concepts of S/MIME and the components in an Exchange 2003-based S/MIME system.
