We often have cases where a customer will open a ticket with us, and then CC: a group email address, either inside or outside their organization. The email address will be a service desk type email like "customer_service@otherorg.org".
The issue is that when the customer service agent replies, ie. "bob@otherorg.org" via email, a new ticket is created that just has that user as the reporter.
How do others solve this issue? We run into it all the time and we spin our wheels closing duplicate tickets and and trying to merge the information from the newly created ticket into the old.
There has got to be a solution for this problem.
