I've created a simple SharePoint 2010 Designer workflow that starts the approval process on a document library. It assigns workflow tasks to users just fine and e-mails the initiator when the workflow has started/completed and when tasks are created for the approvers.
I read that out of the box, SharePoint will automatically e-mail the task recipients if their task is overdue, but I have not seen this behavior. I've tried manually starting the "Notification Timer Job" to force the overdue emails, but none were sent. Is that the timer job that is responsible for sending notifications for overdue tasks?
Also, how can I manually force the overdue task emails to send on my dev machine to test and demo to users?
