Journal Rules & Archive Destinations

The question it answers: Which journal rules copy mail to which archive destinations, inside or outside the tenant?

Journal rules send copies of mail to an archive - often a third party outside the tenant. That is a deliberate data flow, but it has to be known, contracted and pointed at the right place.
