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.

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\OneNote\Addins or HKEY_CURRENT_USER\SOFTWARE\Microsoft\Office\OneNote\Addins.

You can also obtain the ProgID 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.
