This policy setting determines whether e-mailed forms that run at the Restricted security level can be opened.
If you enable this policy setting, users will not be able to open e-mail forms that run at the Restricted security level. Typically, this policy setting is only enabled if you do not wish e-mail forms to be opened at all, which means that the following policy settings would all need to be enabled as well.
- Disable e-mail forms from the Full Trust security zone
- Disable e-mail forms from the Internet security zone
- Disable e-mail forms from the Intranet security zone
If you disable or do not configure this policy setting, InfoPath e-mail forms running with the restricted security level can be opened.
