Users receive notifications in the following scenarios:
Task Activation:
Occurs when a workflow is created, a task is completed (making the next task active), or a task is reverted.
Reminder Threshold:
Triggered when the automatic reminder threshold or a specific task's reminder date is reached.
Task Overdue:
Notifications are sent daily until the task is completed or its due date is adjusted. The overdue email will generate DAILY until the task is complete or the due date is changed so it no longer is overdue.
