Summary

With mobility built in to Exchange Server 2003, an organization no longer needs to decide whether it wants to add mobility. There are no special servers that need to be added to the network and no special add-ins to load on the servers. Exchange administrators choose whether they want to enable the Pocet PC and the Outlook Mobile Access capabilities for the organization, or to disable the functionality organizationwide for a future date.

The other key decision when rolling out mobility functions across an organization is the infrastructure to support the users connecting to the mobile servers. Front-end servers can be set up and dedicated to enable better scalability and isolation of security to a limited-scope server. For a smaller organization, combining front-end and back-end functions into a single server is frequently more economical and makes a simpler messaging environment. Fortunately with Exchange 2003, an organization can start with a combination front-end/back-end server configuration, and then split off the front-end to a separate server at a later date if the organization wants separate server functions.

The task of providing mobility to users is a relatively simple process, with much of the setup and configuration focused on the mobile devices, covered in Chapter 24.
