Hi,
We have an issue that I'm fairly certain can't be all that uncommon.
We have recently started using Jira Service Management when communicating with our customers. A lot of our customers have ITSM systems of their own, some of them use ServiceNow for example.
So a typical scenario for us is that we send them an email from the same email address as our Jira SM is ingesting from. This creates a ticket in their ServiceNow, let's call it "INC00001".
They then send us an email from ServiceNow, which creates a ticket in our Jira SM. Lets call this ticket JSM-01.
When we reply in JSM-01, the subject line of the response will be something like "JSM-01 - INC00001", which is not recognized by ServiceNow, probably because our ticket prefix is in the beginning of the subject line. So it creates a new ticket for them called "INC00002 - JSM-01 - INC00001". And it kind of spirals out of control from there.
This obviously causes a lot of irritation. Has anyone been in the same situation? Has this been solved before?
