Hi all

I have a requirement to send an email notification to a group when an incident status has not been changed within a 2 hour period from the time it has been created.

I attempted to accomplish this by creating two rules as per “Create a Rule that Sets the Escalation Level” documentation.   See enclosed document that shows the rules I have set up.

The issue is that I am not receiving the email notification. 

Questions:

Is using rules to send the email notification the right approach, or is there a better way of accomplishing the task?
