I'm testing Jira service desk in the cloud and I have a question related to incoming mail management.
A customer sends a mail to jira service desk E-mail address to report a problem. A new jira service desk ticket is created with an ID. If the customer sends new mail containing the ticket ID, this mails will be added to the service desk ticket.
How to configure service desk so that if a colleague of the customer sends a new mail containing the ticket ID, this E-mail is also added to the jira service desk ?
I made many tests and the mail sent by the colleague always creates a new Jira service desk ticket.
