We are in the process of the final stages of implementation and tweaking our Enterprise PDM (2012) install, and I'm having difficulty getting the workflow notifications to work.

I have tested the PDM email system, and that works fine.  I can send messages to and from various accounts, but I cannot get a notification to trigger when a certain workflow state is met, or a certain transition is used. 

For example, we have a transition called "Submit for Approval" that goes between a "Work in Progress" state to "Awaiting Approval".  I've tried configuring the notification on the transition and also when the "Awaiting Approval" state is reached.  I have not had any luck with triggering the notifications automatically with workflow state changes or transitions.

I've even tried creating a small 2-state, 1-transition workflow to test things, and that didn't even work.

I know this is a very vague question, in that these systems can be complex, but does anyone have any ideas of things I can check or try?

Thanks.
