Client Update – August 2019

This update (Kb 4475564) took the Office-2013 based client from 15.0.5153.1001 to 15.0.5159.1000 – although the KB lists it as 15.0.5163.1000.

This is the client fix itself:

  • x86 (lync2013-kb4475564-fullfile-x86-glb.exe)
  • x64 (lync2013-kb4475564-fullfile-x64-glb.exe)
