It is a bit strange of a behavior, but when a technician creates a ticket, they can assign to another tech at the same time they create the ticket.  But the notification email is not sent.  The general new ticket email is, and if you go back into the ticket and assign it, it does send the notification email to the assigned tech.

 

Any ideas, we would like other techs to be able to assign tickets to each other when it is not their area or responsibility.
