I have a help desk project. The user always creates tickets via email. This gives us the title and description of the ticket.
However, they now also want to be able to set the due date for the ticket.
I have added the due date field so that if user creates a ticket through the portal, then they can add this field. However I would like to know
1) How can the customer add the due date field to already existing tickets?
2) Is there a way the customer can populate this field through email?
