Are you an IT manager or a partner working with a company needing additional flexibility around user management with Lync?
Stefan Plizga has a tool http://lumt.codeplex.com/ described as: Lync User Management Tool (LUMT) enables administrators to manage contacts, ACEs and Privacy settings on behalf of Lync Server 2013 users.
Watching our MVP community discuss this tool, the ACE (Access Control Entries) and Privacy settings are key draw for this tool.
Disclaimer - I have not installed and used the tool in my lab at this time.
does it work with Lync 2010 also ?
