Address List Segregation and Lync



Is it possible to provide users with an Address List in Lync that only contains a subset of users in a Lync organization?




Using an attribute called msRTCSIP-GroupingID, as described in this TechNet article:

Time to test Smile

I’m gonna use the objectGUID of an Organizational Unit called Zaventem, that I have in my demo environment


Then I’m going to change the value of the msRTCSIPGroupingID for a user in that OU to that objectGUID, in this example Annelies Bulkens:


And I’m doing the same thing for a Lync-enabled user in a different OU, namely DemoTechEd:


Time to check Smile When I log in as my own demo account, I get the following results when entering d:


I don’t see DemoTechEd!

When Annelies does the same thing, she only gets DemoTechEd:


It is still possible for Annelies to add a user as a contact when entering the correct SIP-Uri, as you can see below for user2@lync.local:

    Is there a 3rd party product that goes beyond what…/gg429725.aspx & msRTCSIP-GroupingID  provides for Lync 2010 which would prevent them from using email contact information or manual entry of contact or phone number information. Please let me know at or – Thanks!

    This attribute can also be set on Distribution lists to include them in the lookups.
    Also, don’t forget the Update-CsAddressBook command to speed up the process, and forcing the client address book to update for testing using the method here:
