External contacts represent people outside your organization who can be displayed in the shared address book and other address lists. External contacts have e-mail addresses outside your organization. They don't have a mailbox in your organization and they can't sign in to your domain.
External contacts are great because they let you maintain an up-to-date organization-wide repository for contacts and help your users collaborate more efficiently with people outside your organization.
