I'm just starting with JSM to see if we can manage our external customer support ticketing. We're not using a portal or web based approach so tickets will be created via Halp coming in from email or Slack. I've set up several test users from outside our domain and linked the with a test Organization. My expected behavior is when I create a ticket either manually or via Halp from an existing Customer, the Organization field would default to the Organization they are assigned to, but I'm having to assign Customers manually each time. Is this expected?
