We are fully implementing Jira Service Desk but still working along with our IT Consultants in which they have their own ticketing system.
When an e-mail is sent to JSD, it also creates a ticket on their system. However when a user or myself adds a comment or reply back to that e-mail, instead of Jira adding the comment, it creates a new ticket on both ours and their system.
I tried to tweak settings such as limiting the messaging threshold from 0 to 1 and put their e-mail address to "bulk ignore" but it kept continuing this endless ticket creating loop.
I appreciate any assistance with this. Thanks!
