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: http://technet.microsoft.com/en-us/library/gg429725.aspx
Time to test
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 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 firstname.lastname@example.org:
