Janelle went to update the last name for one of her group contacts. She double-clicked on the contact, changed the last name, and closed the contact by clicking the red X in the top right corner. Which statement best explains why the contact did not update? Janelle should have right-clicked on the contact and clicked Modify. Contacts cannot be updated once they are saved as part of a group contact. Janelle should have clicked Save & Close to close the contact. Contacts can only be updated by re-entering all of the information for the contact.
