Case team assignments identify the people responsible for the case. They also contribute to case visibility for users whose access depends on assignment.
Assignment changes require Full Access and Assign/Unassign Case Users. Users offered in the selectors must satisfy role eligibility and active-access requirements. A missing person may be inactive, ineligible, already assigned, or outside the available scope.
Assigning someone to the case is separate from assigning a specific task or event. Check the assignee on each activity when distributing work.
Review their outstanding tasks and events and arrange reassignment where needed. Removing a case assignment can affect their ability to access the case.
