When a meeting is created, the user can choose to create a calendar event at the same time.
When a calendar event is created it sends out notifications. These notifications feel like duplicates because the meetings portlet already handles the notifications.
It would be preferable to have events created from the meetings portlet not send out notifications.
To implement this, a change will have to be made to the calendar portlet to allow a parameter to be passed in when creating and updating an event that will disable notifications during that action.
If the calendar event is modified from the calendar portlet, the calendar event should still send a notification.
