We have set up Email-to-Case for our org and we want to implement this requirement:
When a user sends an Email from the Case to a customer, the customer's reply should always create a new Case.
I know that is not optimal behavior, but it stemmed from the requirement to create new Cases when a new reply comes to a Closed Case. But now we want it for all of Cases.
I tried to remove the Thread Id from the emails by deselecting this 2 checkboxes but still the replies are tied to the existing Case. How can I implement this?
