INTRODUCTION
This article discusses how Microsoft Internet Security and Acceleration (ISA) Server 2006 or ISA Server 2004 and Microsoft Outlook Web Access work together to provide enhanced security for Outlook Web Access servers.
MORE INFORMATION
ISA Server and Outlook Web Access work together to enhance security for Outlook Web Access servers. Outlook Web Access provides Web browser access to the following items:
- E-mail messages
- Scheduling, including group scheduling
- Contacts
- Collaborative information that is stored in Microsoft Exchange Storage System folders
Outlook Web Access is used by remote, home, and roving users. When you publish Outlook Web Access servers by using ISA Server, you help protect the Outlook Web Access server from direct external access because the name and the IP address of the Outlook Web Access server cannot be accessed by the user.
The user accesses the ISA Server computer, and ISA Server then forwards the request to the Outlook Web Access server. This behavior follows the mail server publishing rule that is configured on the ISA Server.
The ISA Server Outlook Web Access publishing feature also enables you to publish Outlook Mobile Access and Exchange ActiveSync.
Outlook Mobile Access gives users access to Outlook from mobile devices. When you use Exchange ActiveSync, you can synchronize to the Exchange mailboxes from Microsoft Windows Mobile-based devices, such as Windows Mobile 2003 Software for Pocket PC, including Pocket PC Phone Edition, and Windows Mobile 2003 Software for Smartphone. Exchange ActiveSync offers a high level of security.
