After a public folder has been created and synchronized in the target organization, the mail-enabled status and "Hide from Address Book" option of the public folder cannot be re-synchronized.
Public Folders mail enabled status and "Hide from Address Book" attribute synchronized during the first synchronization session.
Delta-Sync is not configured to change these parameters.
To change these options you must perform re-synchronization of the Public folders by checking "Enable specific synchronization options for the next session" and choose "All" or "Only folders permissions, rules and folder-associated information" option under "Items to resynchronize" .
