Lync 2013 / SfB 2015 Client Update – July 2017

It’s been 3 weeks since our last update to the Office 2013-based Lync/SfB client. Today we go from 15.0.4933.1000 to … 15.0.4933.1000 – although the article (kb3213574) and other evidence – see below – confirms it’s 15.0.4945.1000.

What’s Fixed

This one contains a solo update:

Kb 4032344 Low Internet Explorer performance when Skype for Business 2015 add-in for Internet Explorer (OCHelper.dll) is enabled.

What’s New / Changed

Nothing documented.

Known Issues

You might think this update hasn’t worked, but it’s just not playing by the usual rules.

Help / About doesn’t show it and it’s not revealing itself to Get-CsConnections either.

It is however all good – it’s just only updated the Browser Helper Add-on – and you’ll find it in IE / Settings / Manage add-ons. (See below).

Pre-Req’s

It’s been a big year for pre-req updates, but if you’re current (to 15.0.4933.100) then you’re OK today.

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).
