 Executive Summary:
Get instructions for publishing Microsoft Outlook Web Access (OWA) hosted on a Microsoft Exchange Server 2007 Client Access server to Internet users through Microsoft ISA Server 2006. Once you've published OWA, you use similar steps for publishing other Exchange services such as Outlook Anywhere (previously known as remote procedure call—RPC—over HTTP), Exchange ActiveSync, Autodiscover, and other applications such as Outlook Express and Outlook Express's Windows Vista successor, Windows Mail. The final step is publishing the Exchange Edge Transport server on ISA Server to communicate with other SMTP servers on the Internet.

One of the most important tasks that administrators of almost every network face is providing remote and mobile users access to internal resources, especially email services. Microsoft Exchange Server 2007 has several services that users can access over the Internet, and if improperly configured, they can pose a significant security risk. However, you can securely publish Exchange 2007 services through Microsoft ISA Server 2006. I'll show you how.

ISA Server Proxies Exchange 2007 Client Access and Edge Transport Servers
ISA Server offers proxy and reverse-proxy functionality, application-level filtering, and intrusion detection to secure Exchange 2007 services from malicious users, as well as provide corporate users the proper level of access. . . .
