In Lync 2010,
I can customize or select contacts' groups by Stored Procedures in Database-[rtc]
Example: UserMgmtSetContact UserMgmtAddGroup,UserMgmtGetGroups,UserMgmtGetContacts .....
But in Lync 2013,
The Database-[rtc] is not existed, and i can not customize contacts' groups in Lync 2013.
So how can I customize that in Lync 2013, however powershell, SDK, Database, C# ... or anything?
