Lync Client Password Recovery

I wrote a small tool that dumps all stored password for the Microsoft Lync Client that I’d like to share here.

  • Running multiple instances of Lync (howto)

    imageYesterday I showed a video demonstrating it’s possible to run multiple instances of the Microsoft Lync 2010 client simultaneously.

    A little warning before we go on: the Lync Client was not designed to run with multiple instances. Or better said: it was designed specifically to prevent this, let’s see how it does this:

    On startup Lync calls an internal function called COcAppNoUI::InitializeMainInstance. In this function it creates a Mutex named “Office Communicator_” in the Global namespace. It also creates an Event in the Global namespace called “COMMUNICATOR-“.

    When a second instance of Lync is launched it checks if the Global Mutex exists and if it does it fires the Global Event. The Main instance has a thread that waits for this event using the WaitForMultipleObjects API.
