Display OLE package objects
Supported on SUPPORTED_Windows7 (defined in the Windows templates)
What it does
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, note that this policy setting only applies if the "Outlook Security Mode" policy setting under "Microsoft Outlook 2016\Security\Security Form Settings" is configured to "Use Outlook Security Group Policy."

- The OMA-URI is an inferred ADMX-backed Policy CSP candidate derived from the source ADMX file name and policy name.
- Some Microsoft policies use built-in Policy CSP pages whose area names don't match the ADMX file name, so verify the candidate against Microsoft Learn before deployment.
