Technical resources are handled as contacts in the Team calendar and can be displayed there. You can assign appointments to these resources if the resource has the Create or Modify calendar release.
You can assign such a resource to an appointment at the staff member by dragging and dropping it on the row of the resource. If the resource is assigned, the appointment appears as a utilization bar in the row of the resource.
Alternatively, the resource can be assigned directly at the appointment in the Participants tab.
