By default, OLE package objects are not displayed in e-mail messages. You can change this behavior so that the package appears in the body of the e-mail message as an icon that represents an embedded or linked OLE object. When users double-click the icon representing the package, the program used to create the object either plays the object or opens and displays it. Be aware that the icon for OLE package objects can be easily changed and used to disguise malicious files. To set Exchange Security Form settings by using Group Policy instead, you must enable the Outlook Security Mode setting in \Security Form Settings\Microsoft Office Outlook 2007 Security and select the Use Outlook Security Group Policy check box.
