Allow scripts in one-off Outlook forms

UserNeeds changes for IntuneL_EnableScriptsInOneOffForms

Supported on SUPPORTED_Windows7 (defined in the Windows templates)

5568.1000

What it does

This policy setting controls whether scripts can run in Outlook forms in which the script and layout are contained within the message. If you enable this policy setting, scripts can run in one-off Outlook forms. If you disable or do not configure this policy setting, Outlook does not run scripts in forms in which the script and the layout are contained within the message. Important: 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."

What it writes

Hive: HKEY_CURRENT_USER
Registry key: software\policies\microsoft\office\16.0\outlook\security
Value name: enableoneoffformscripts
When enabled: DWORD 1
When disabled: DWORD 0

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.
