Lync 2013 Server Update – April 2016

An April update to the Lync 2013 server has landed, taking the server from 5.0.8308.945 to 5.0.8308.949. Five components are patched, however as at this date (April 16th) the Kb article – or at least the version dished by Microsoft’s CDN to me in Sydney – hasn’t been updated with the content, and one of the Kb articles referenced in the installer (Kb3140584) is giving “This page does not exist”.

What’s Fixed?

This cumulative update fixes the following issues:

  • Kb3148961 Event ID 56417 when the window title of combined programs exceeds 128 characters in Lync Server 2013

Here’s the ‘before” view of it going on to my Standard Edition Front-End:


If you’re not reading the fine-print in How to apply this update you might miss this additional installation step:

“To make the [new SLA] cmdlets available over Windows PowerShell Remote Management, run the Update-CsAdminRole command one time from a Lync Server Management Shell”.


Yes, the process prompts you to reboot at its completion.
