we have a number of service desk request types, which I have linked to workflows with each status having a unique name.
When a customer logs a ticket through the portal, they get a confirmation of receipt email, and when the JIRA is resolved, they get an email stating it's resolved and to provide feedback on the experience. Hey also get emails from comments to the customer.
However, the customer doesn't receive any emails noting that the status has changed, and hence they are in the dark up until the JIRA is closed. He doco states that they should be notified as long as the customer status for the request type is not the same as the status, which I have confirmed is not the case.
