I am going through my customer list and determining which customers have access to what. I give all of my customers a project role of "Servicedesk customer" to their individual projects. I want to know what additional access/rights or lack of access/lack of rights my customers will have if I make them part of an external group and put them into that external group for their project but also make them a service desk customer at the same time? What happens if they are not assigned any project roles like service desk customer, but they are part of an external group for their project? I hope you understand my question. Thank you so much.
