Is there a way to control the users that are populated in the ABS file or is there a way to filter the address book based on an AD Attribute?
Answer – The users populated in the ABS files can be controlled based on certain AD Attributes listed in the ABAttribute table. One such attribute used for filtering is the msExchangeHideFromAddressBook. This is a User attribute added by the Exchange schema. Exchange uses this to hide the contact from Outlook Global Address List, if the value is equal to True. In the same way if the value on this attribute is True, UR does not include that user in the ABUserEntry table and hence this user will not be in the ABS files. There are 5 other attributes – mailNickname, msRTCSIP-PrimaryUserAddress, telephoneNumber, homePhone and mobile that can be used for filtering users. A user has to have a value for at least one of these attributes to appear in AB files. For example, if you do not want service accounts to appear in AB, you might try deleting these 5 attributes from service accounts.
