I have had some questions from users regarding email notification settings on Tasks.  In Classic, there is an option to send an email notification.  In Lightning, this option does not appear.  I know in Classic if "Enable User Control over Task Assignment Notifications" is setup then users can select "Email me when someone assigns me a task" under Settings > Calendars & Reminders > Activity Reminders.  This setting is not available to users in Lightning.  To ensure that the users receive notifications, is there something I need to setup in Lightning?
