Microsoft Exchange Server 2007 provides several enhanced features for the information worker. These features include Microsoft Exchange ActiveSync, Office Outlook Web Access, Outlook Anywhere, and Unified Messaging. By using these features, information workers can access their messaging data from a wide variety of locations and on a wide variety of devices.
Exchange ActiveSync is a Microsoft Exchange synchronization protocol that is optimized to work together with high-latency and low-bandwidth networks, such as cellular networks. The protocol, based on HTTP and XML, lets devices such as browser-enabled cellular telephones or Microsoft Windows Mobile powered devices access an organization's information on a server that is running Exchange 2007. Exchange ActiveSync enables mobile device users to access their e-mail, calendar, contacts, and tasks and to continue to be able to access this information while they work offline.
Outlook Web Access
Outlook Web Access enables access to your Exchange mailbox data from a Web browser. There are two different versions of Outlook Web Access: Outlook Web Access Premium and Outlook Web Access Light. Outlook Web Access Light supports accessibility features for users who are blind or have low vision, and it will run on most Web browsers. It provides a simplified user interface and reduced feature set compared with Outlook Web Access Premium. Outlook Web Access Premium requires Internet Explorer 6 or a later version and provides features that are currently unavailable in the Light version, such as Unified Messaging and Tasks.
Unified Messaging combines voice messaging, fax, and e-mail messaging into one store that can be accessed from a telephone and a computer. Exchange 2007 Unified Messaging integrates Exchange Server with telephony networks and brings the Unified Messaging features to the core of Exchange Server. Unified Messaging lets users access voice mail, e-mail, fax messages, and calendar information that is located in their Exchange 2007 mailbox from an e-mail client such as Outlook or Outlook Web Access, from a mobile device that has Exchange ActiveSync enabled, such as a Windows Mobile powered smartphone or a personal digital assistant (PDA), or from a telephone.
The Outlook Anywhere feature for Exchange 2007 enables Office Outlook 2007 and Outlook 2003 clients to connect to their Exchange servers over the Internet by using the RPC over HTTP Windows networking component. This eliminates the need for users to create a virtual private network (VPN) connection to your organization's network when they are using Outlook 2003 or a later version.
Other Client Features
Exchange 2007 provides e-mail access for clients by using Post Office Protocol version 3 (POP3) or Internet Message Access Protocol version 4rev1 (IMAP4). POP3 provides access to your Inbox data. IMAP4 provides access to data in the Inbox in addition to other folders in your Exchange mailbox.
