Product version: Lync 2013

One of the most common checks that we do when troubleshooting Lync client issues is determining whether you are running the latest version of the Lync client and if all patches are installed.

A majority of the Lync client issues that get reported are resolved by upgrading to the latest release or update of the product. Thus, we highly recommended that you install the latest version of the Lync client, along with the latest updates, before you contact Microsoft Product Support. This article will help you identify the correct release version number.

To check the client version, from within your client, navigate to About Microsoft Lync, as shown in Figure 1 below.

The version number in Lync 2013 is usually within the brackets on the very first line, as shown in Figure 2 below (15.0.4481.1000).

Another way to check the client version is to look at the client UCCP log (Lync-UccApi-*.uccapilog, usually located in %localappdata% \Microsoft\Office\15.0\Lync\Tracing folder) and look at any of the outgoing messages. For example, look at the initial REGISTER sent from the client, as follows:

03/19/2013|13:52:48.932 32B4:D24 INFO :: REGISTER sip:microsoft.com SIP/2.0

Now that you have the version number, how do you know which release is running on the client?

Each update (All Lync updates are cumulative updates) that is released by Microsoft for Lync has its own version number. You can determine the version number associated with an update by looking at the related KB article and noting the version of 'Lync.lync.exe' in the File Information section of the article.

For quick reference, the following table lists the versions, release month, year, and a link to the KB article for all Lync 2013 updates released through August 2014:
