Make a notification mandatory

To prevent users from turning off or deleting a subscription to a notification, make the notification mandatory.

1. Navigate to System Notification > Email > Notifications.
2. Open the appropriate notification.
3. Configure the form and add the Mandatory field. This field does not display by default.
4. Select the Mandatory check box.

   That notification is now locked in user preferences, preventing the user from removing or unsubscribing to the notification, filtering it, or changing the schedule. In the user's notification preferences, the control button for the mandatory notification is on and is read only.
