Does anyone know what key and value in the registry enables\disables the email icon? Is it even a registry key? I know that it can be done manually via the UI. Can it be done using Adobe Customization Wizard 8? I have Adobe Acrobat Standard 8 and Reader 4 installed on a Citrix server and would like the default value for the email icon to be set to disabled or even hidden when users open a PDF file.
