Lync 2013 / SfB 2015 Client Update – February 2017

Our February update fixes a handful of issues in the Office 2013-based Lync/SfB client (KB3161988), and in so doing it takes us from 15.0.4893.1000 to 15.0.4903.1001.

What’s Fixed

This update fixes the following issues:

  • Kb4010268 Make High Importance IM messages more prominent in Skype for Business 2015 (Lync 2013)
  • Kb4010264 “Search Chat Room History” pushes OK/Cancel buttons off the bottom with controls in Skype for Business 2015 (Lync 2013)

  • Kb4010270 The location won’t be published after you update it in VDIv2 in Skype for Business 2015 (Lync 2013)

What’s New / Changed

Nothing documented.

Known Issues

None documented.


There are no changes here from recent updates, so if you’re already current you only need the patch itself, below under “Download”. If however your patching isn’t to current, then 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).
