Lync 2013 Server Update – July 2015

July 10th saw an update to the Lync 2013 Server components. In a break with tradition, *every* installed component gets an update, so now they’re all at 5.0.8308.920. The reasoning for this is not yet clear.

What’s Fixed?

There are a handful of fixes, but lots of generic “improves the reliability, stability, and performance of…”.

  • Kb 3070715 RTCSrv.exe crashes when the process is selected in Resource Monitor tool in a Lync Server 2013 environment
  • Kb 3070718 CPU usage percentage of the RTCSrv.exe process is high on a Lync Server 2013 front-end server
  • Kb 3070721 Lync Server 2013 Front End service cannot check conference service availability
  • Kb 3051963 Lync Mobile Client call is dropped immediately when you dial 0 for an operator
  • Kb 3062801 Lost data when Lync Server 2013 directories move to Skype for Business
  • Kb 3070713 This cumulative update resolves an issue in which Lync Server 2013 response group usage report takes longer time to run
  • Kb 3070720 This cumulative update resolves an issue in which participants cannot see your video when you join an online meeting through B2BUA
  • Kb 3070717 This cumulative update resolves an issue in which call park orbit number is not displayed in Lync Server 2013

What’s New?

Nothing apparent just yet.



Here’s the ‘before” view of it going on to my Standard Edition Front-End. That’s LOTS of red for a machine that’s otherwise current:
