Path in the GPO console

User Configuration\Administrative Templates\Microsoft Outlook 2016\Form Region Settings

Description

By default, all form region customizations are permitted to run in Outlook. By using this setting, you can disable all form region customizations, or specify that form regions must be registered on a per-computer basis, rather than a per-user basis.

Registry

HKCU software\policies\microsoft\office\16.0\outlook\addins

More options available

Options

Configure form regions permissions:
disableformregions enum
  • All form regions are allowed to run -> 0 (default)
  • Allow only those registered in HKLM -> 1
  • No form regions are allowed to run -> 2

Export Builder

BETA

Configure the state, scope and options, then generate .reg, PowerShell, Intune and SCCM outputs — or add the setting to a multi-setting collection.

These exports write the registry — this is not a managed GPO.
