  • Unable to create group, add or pin contacts that also have Lync accounts in our company. I can contact but need to search every time for the contact. I am using a MacBook Air with the latest OS and applications. It appears to be only a MAC issue because other contacts using MS Windows are not having this problem.

    Please provide a solution.
