Hide users from address book in Skype for Business
SfB On-Premise is making use of the Exchange GAL.
If you don't want users or other resources to appear in address book / GAL search in the Skype for Business client there is an easy way. Hiding contacts from GAL, by changing an AD related attribute. This could be e.g. hiding Helpdesk Team Members
This is the Exchange attribute for hiding users from the Global Address List (GAL). If this is set to TRUE, which indicates it doesn’t need to appear on the GAL, Lync will also ignore this user for the Address Book.
This sets the attribute "msExchHideFromAddressLists" to True.
