  1. Can you give a description and a reason for each of the flags? Particularly, msExchModerationFlags=”6″ and msExchAddressBookFlags=”1″; possibly msExchProvisioningFlags=”0″. We’ve been going through our hybrid system, trying to make sure we’ve got things right. Usually, it works without any of the three that grabbed my curiosity above.
