Microsoft Lync is fast, secure, and convenient enabling quick chats even if you are not in the office. It is compatible with your system since Lync easily integrates with Outlook and has versions that can be used by Windows, Mac, iPhone, and Android. It can provide a real-time availability status ("presence") of other staff members since it automatically adjusts and presents user status and availability within Outlook, SharePoint, and in many other programs, and also has options for setting levels of privacy.
