Rest assured this is not a question of disabling notifications all together. This is about removing notifications to a specific user, in the middle of a ticket cycle.
Scenario/Needed:
-On a specific transition change, I would like to send a one-time notification email to a generic email address.
Solution found:
-Because Jira seems to be only able to email email addresses (users) that are added to a ticket, I have registered the generic inbox as an Atlassian User and given access accordingly to our service projet.
-On that specific transition change, representing that the ticket now needs to be handled by Team X, the generic EmailBoxUser is added as a Requested Participant, and then an event is fired to send an email to this EmailBoxUser.
By-product issue:
-Even if the EmailBoxUser is removed from the Request Participant field, it continues to receive notifications.
Needed: To remove those notifications without a human intervention.
Thanks!
