Hello there.
I have this scenario:
We have only one email address configured at ServiceDesk Plus for all our technicians. Sometimes occurs when "Technician 1" sends a reply from a customer's message ("customer 1") which belongs to Request ID "X"; this reply is sent to another customer (not "Customer 1"), in another Request ID (not request ID "X"). This is a new situation, and we haven´t had another similar case but since a week ago. This scenario has been given at least 4 times more, with different technicians, and different customers.
We have ServiceDesk Plus version 9.1.
Regards.
