List of managed add-ins

This policy setting allows you to specify which add-ins are always enabled, always disabled (blocked), or configurable by the user. To block add-ins that are not managed by this policy setting, you must also configure the "Block all unmanaged add-ins" policy setting.

To enable this policy setting, provide the following information for each add-in:

In "Value name," specify the programmatic identifier (ProgID) for COM add-ins, or specify the file name of Word add-ins.

To obtain the ProgID for an add-in, use Registry Editor on the client computer where the add-in is installed to locate key names under HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\Word\Addins or HKEY_CURRENT_USER\SOFTWARE\Microsoft\Office\Word\Addins.

To obtain the file name of an add-in, click the File menu in the application where the add-in is installed. Click Options, click Add-ins, and then use the Location column to determine the file name of the add-in.

You can also obtain the ProgID or the file name of an add-in by using Office Telemetry Dashboard.

In "Value," specify the value as follows:

To specify that an add-in is always disabled (blocked), type 0.

To specify that an add-in is always enabled, type 1.

To specify that an add-in is configurable by the user and not blocked by the "Block all unmanaged add-ins" policy setting when enabled, type 2.

If you disable or do not enable this policy setting, the list of managed add-ins is deleted. If the "Block all unmanaged add-ins" policy setting is enabled, then all add-ins are blocked.

To specify that a Word add-in is always enabled, in addition to configuring this policy setting, you must also specify a location that is used as a trusted source for open files in Word. To do this, configure the "Trusted Locations" policy setting at User Configuration\Administrative Templates\Microsoft Word 2016\Word Options\Security\Trust Center, and then move the add-in file into the trusted location.
