For each individual that is now a part of the Exposed Contacts list, a Case Task must be created and assigned to whoever will follow up. Follow the Create a Case Task guide to create a task for each exposed contact.
Each Case Task must be completed before moving forward, so follow the Complete a Case Task guide for each task before continuing.
Once each Case Task has been completed, and closed, the original case can be closed. Follow the Close a Case guide to close the original case record.
