6. On the File Access tab, use the check boxes to configure the file access and viewing options for users. File access lets a user open or view the contents of files attached to an email message.
   
   File access can be controlled based on whether a user has signed in on a public or private computer. The option for users to select private computer access or public computer access is available only when you’re using forms-based authentication. All other forms of authentication default to private computer access.

   • Force WebReady Document Viewing when a converter is available   Select this check box if you want to force documents to be converted to HTML and displayed in a web browser before users can open them in the viewing application. Documents can be opened in the viewing application only if direct file access has been enabled.
