Professional Windows® PowerShell for Exchange Server 2007 Service Pack 1

Configuring the Client

Access Server Role

The Client Access Server (CAS) plays a similar role to the Exchange Server 2000 or 2003

Front - End computer. It provides client access to Office Outlook Web Access (OWA), Exchange

ActiveSync (EAS), Outlook Anywhere, IMAP4, and POP3. The CAS also provides new services —

Autodiscover, the Availability Service, and Exchange Web Services. Autodiscover will automati-

cally create Office Outlook 2007 profiles for users by just entering their email address and

password. The Availability Service provides calendaring information, such as free/busy for

Office Outlook 2007 clients. Exchange Web Services is an interface for building applications

integrated with Exchange with the Microsoft .NET platform.

Unlike the Exchange Server 2003 front - end server, the CAS handles more processing to lighten

the work done by the Mailbox role. There must be at least one CAS deployed in the organization,

and at least one per Active Directory site where there is a Mailbox role. This chapter helps an

administrator understand and configure the services provided by the CAS.

This chapter covers the following topics:

❑ Working with user settings

❑ Configuring POP3 and IMAP4

❑ Configuring certificates

❑ Working with Autodiscover, proxy, and redirection

❑ Working with Outlook Anywhere

❑ Working with the Offline Address Book
