Se aplica a: Exchange Server 2010 Última modificación del tema: 2009-05-18
In Microsoft Exchange 2010, there are five server roles you can install and then configure on a computer that's running Windows Server 2003. This topic provides an overview of the Client Access server role. The Client Access server role supports the aplicación web de Outlook and Microsoft Exchange ActiveSync client applications and the Post Office Protocol version 3 (POP3) and Internet Message Access Protocol version 4rev1 (IMAP4) protocols. The Client Access server role also supports services, such as the Autodiscover service and Web services.
The Client Access server role accepts connections to your Exchange 2010 server from many different clients. Software clients such as Microsoft Outlook Express and Eudora use POP3 or IMAP4 connections to communicate with the Exchange server. Hardware clients, such as mobile phones, use ActiveSync, POP3, or IMAP4 to communicate with the Exchange server. The Client Access server role is required in every Exchange 2010 organization.
