Hide contacts by making them 'inactive' when they are no longer part of the active project team. This stops any future communications going to the contact.
Organisation menu > projects
Project menu > Details > Contacts
Select the pencil to the right of the contact you want to set as inactive > Set inactive
Tips!
If the contact record has been used on a project invoice it cannot be deleted.
