The field description states "Indicator regarding whether email has been processed or not, when customer disables creation of new Task.Assignments to process new emails"
Furthermore, the help documentation states: "This applies only to incoming emails. After the email listener processes the email, appropriate action is taken (per your configuration) and the processed flag is set to true"

Thanks for the response. There is a checkbox on the Journal Email for ex, in an Incident Activity History if I add an email what is the need to have a check box for processed?
Just to be clear - I am wondering why there is a "Processed" box on the Journal Email UI for out going email when "Processed" only applies to inkling email. I checked the back end and it is the same field.
It seems that is the case simply because that is the only form available, so both Incoming and Outgoing emails use the same layout.
