Lync 2010 on-premise Enterprise.
We're trying to make sure that folks/contacts cannot be searched for from other departments/Organizations.
When I start to type "Chr" it lists all users who start with it, Chris, Christen, etc. If it meant only that you could add someone if you knew their entire SIP URI then I'd be ok with that.
Any ideas how this can be restricted by OU or globally?
