What is the difference between Not Shared and Cannot be Shared on contact types?
Note: Contact sharing is removed in The Education Edge version 7.87 patch 3 and higher if The Education Edge is integrated with The Raiser's Edge. If your Education Edge database is not integrated with The Raiser's Edge, contact sharing functionality is unchanged in 7.87 patch 3 and higher.
A Not Shared contact type is not shared because the address is not shared. Once the address is shared, the contact type will be shared.
A Cannot be Shared contact type will never be shared regardless of whether the address has been shared.
