I went to look for the client uccapilog file, but it wasn't in the location I was expecting.  In previous versions of Communicator and Lync 2010, the client tracing folder was stored in:


In Lync 2013, the client tracing folder in now stored in the following location:


  • Yes, because Lync 2013 is now integrated in Office 2013, so the path also for the User configuration is changed to the office path C:\Users\<username>\AppData\Local\Microsoft\Office\15.0\Lync

  • Do you know how often this log is over written?

    The log files are overwritten every time the Lync 2013 client is launched.  However, there is a Lync-UccApi-x.UccApilog.bak file that persists.  If you leave the Lync 2013 client running for awhile, you'll notice that the .UccApilog file will roll over to a new file at 50MB, so you can have multiple .UccApilog files in the Tracing directory.

  • Guys, I have an annoying problem, my phone in the Lync which I'm using as frontend for Communicator server is stuck on an older extension I used to occupy. now I'm not able to delete this extension from my Lync and that actually publishes in the outlook too... Can anyone help?
