This January update (Kb3114502) takes the Office 2013-based Lync/SfB client from 15.0.4779.1001 to 15.0.4787.1001.

  • Kb3128747 Video is missing in a Skype for Business 2015 meeting recording after the December 2015 security update 3114351 is installed

  • Kb3132305 “An unknown participant is now joining” message is displayed in a transferred call in Lync 2013 (Skype for Business)
  • Kb3132304 The Lync 2013 (Skype for Business) user interface of a call monitor flashes constantly
  • Kb3114687 “The address type is not valid” error when you sign in to Lync 2013 (Skype for Business) by using domain\username format

What’s New / Changed

None documented.

Known Issues

  • Kb3051158 “Help isn’t working” error occurs when you open the “Skype for Business Help” window in Skype for Business
  • Kb3051160 Cannot join meetings by using Lync 2010 after you install OneDrive for Business

A few people have found their recent updates haven’t delivered as expected. Don’t forget *all* of the pre-req’s. The Office 2013 SP1 requirement still applies if you’re using Outlook 2010. (Lync 2013 in all of its flavours – e.g. Lync Basic – is still a component of Office 2013).



Current Version


Microsoft Office 2013 Service Pack 1 (KB2817430) 1.0 18 February 2014
Update for Office 2013 (KB3054853) (NOTE 1 BELOW) 1.0 9 June 2015
LyncHelpLoc (Kb3039776) 1.0 1 December 2015
Microsoft Office 2013 Language Pack Service Pack 1 (KB2817427) 1.0 13 February 2014

NOTE1: “You do not have to apply update KB3054853 if you applied the April 14, 2015, update (KB2889923) or the May 12, 2015, security update (KB3039779) for Lync 2013 (Skype for Business)”


This is the client fix itself:

  • x86 (lync2013-kb3114502-fullfile-x86-glb.exe)
  • x64 (lync2013-kb3114502-fullfile-x64-glb.exe)


I have all the pre-req’s already installed, so a reboot was not required. I was however running Outlook 2013 at the time and I was prompted to exit it, to which I duly complied.
