Summary: This article, by ISA Firewall specialist Thomas Shinder, explains that earlier versions of ISA Firewall (2000 and 2004) included navigation protection.  Navigation protection ensures that if a user goes to another website, such as Google, without logging off OWA, ISA automatically logs the user off.  With navigation protection, administrators can rest assured that users are not leaving active OWA sessions behind.

ISA Firewall 2006 no longer includes navigation protection.  This is explained in more detail in an ISA Security report published by Messageware Incorporated (ISA Security Report: OWA Security Issues Undetected by ISA Server) referenced in Thomas Shinder’s article.

Summary: Many companies who have Microsoft Exchange with the update Q911829 (released in March and April, 2006) installed and are using Outlook Web Access have been experiencing a problem addressing messages. In some environments, when the spacebar is pressed after addressing a message the address dialog box re-appears and in some cases, while typing the message body, entering a space suddenly activates the addressing dialog box.
Upon hearing about this problem from Exchange administrators who were concerned about the productivity of their users, Messageware researched the problem, found the cause, and has released a free fix. This patch is now available to companies and Exchange administrators who are running any version of Exchange or OWA. It can be downloaded at http://www.messageware.com/fixQ911829.
