This policy setting controls whether notifications about the Workplace Discount Program (previously named the Home Use Program) are displayed to end-users in Office applications. If you enable this policy setting, Office will occasionally notify end-users if they are eligible to purchase an Office subscription for their personal use at a discount via the Microsoft Workplace Discount Program. End-users can permanently opt-out of these notifications at any time using a button within the notification. If you disable this policy setting, Office will not display any notifications related to the Microsoft Workplace Discount Program. If you don't configure this policy setting, Microsoft will control whether or not these notifications appear. Please check the Message Center in the Microsoft 365 admin center for updates on whether this feature has been enabled by Microsoft yet and the default setting for the notifications. For more information, see https://go.microsoft.com/fwlink/p/?linkid=2202543. Note: This policy setting only applies to subscription versions of Office, such as Microsoft 365 Apps for enterprise, and to subscription versions of Project and Visio.
