Objective 1.4: Design Client Access
Client Access Servers (CAS) allow users to connect to their Exchange mailboxes, whether they are located on the same local area network or connecting remotely through Outlook Anywhere, VPN, Outlook Web App, or DirectAccess. When you are designing your organization’s CAS deployment, you need to ensure that for every site with a mailbox server you have at least one CAS. In this objective, you’ll learn about the factors you need to consider when creating a Client Access Server design for your organization. In Chapter 2 you’ll learn about how to configure CAS to provide these services to users on your organization’s network.
