Lync 2013 / SfB 2015 Client Update – January 2019

Happy new year! I wonder what 2019 has in store for us?

It’s been 6 or so weeks since our last update to the client, and this update brings just the one fix. Kb 4461557 takes the Office 2013-based client from 15.0.5085.1000 to 15.0.5101.1000 (although it’s reported in the kb as 15.0.5101.1002).

What’s Fixed

This update fixes the following issue:

What’s New / Changed

Nothing documented.

Known Issues

Nothing documented.


It’s all good if you’ve been diligent in your patching.

If however your patching isn’t to current you’ll need to check you have *all* of these 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


Update for Office 2013 (KB3054853) (NOTE 1 BELOW) 1.0 9 June 2015
LyncHelpLoc (kb3191937) 1.0 22 May 2017
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-kb4461557-fullfile-x86-glb.exe)
  • x64 (lync2013-kb4461557-fullfile-x64-glb.exe)


I have all the pre-req’s already installed, had exited the client before we started & was not prompted for a reboot.
