Turn off user customizations via UI (Microsoft 365 Apps Group Policy)

What it does

This policy setting can prevent users from customizing both the Quick Access Toolbar and Ribbon through the user interface (UI). If you enable this policy setting, the following UI entry points are turned off: the Quick Access Toolbar and Ribbon tabs in the application's Office Center dialog box, and the Quick Access Toolbar and Ribbon customization options on the right-click menu on the Ribbon. If you disable or do not configure this policy setting, users can customize the Quick Access Toolbar and Ribbon through both the application’s Office Center dialog box, and the right-click menu on the Ribbon.

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.
The generated payload is incomplete because one or more ADMX element values were not supplied: L_DisableToolbarCustomizationUIWord, L_DisableToolbarCustomizationUIExcel, L_DisableToolbarCustomizationUIPowerPoint, L_DisableToolbarCustomizationUIAccess, L_DisableToolbarCustomizationUIOutlook, L_DisableToolbarCustomizationUISPD, L_DisableToolbarCustomizationUIPublisher, L_DisableToolbarCustomizationUIProject, L_DisableToolbarCustomizationUIVisio, L_DisableToolbarCustomizationUIOneNote, L_DisableToolbarCustomizationUIInfoPath, L_DisableToolbarCustomizationUISPW
