Lync Server 2013 November 2016 Cumulative Update 8 HF 1

Saw this last week and got some time to read up on the CU and wanted to wrote a quick summary and video of CU install process. Whilst researching this CU i came across Grieg’s blog post which i highly recommend reading  here and also Guy Bachars blog here

On review on Grieg’s post and Microsoft documentation the key feature that most people will be running to get the November 2016 CU is enabling the Mac client with Lync Server 2013.

But PLEASE NOTE when installing the CU there are additional steps that are required to complete the installation so please don’t miss these.


Step 4: Enable the Mobility service

To enable the Mobility service, run the following cmdlet:


Step 5: Enable the Unified Communications Web API

To enable the Unified Communications Web API (UCWA), you must run the Bootstrapper.exe tool again on all Lync Server 2013 Director servers, Standard Edition servers, and Enterprise Edition front-end servers on which the web components are installed and updated. The command to run the tool is as follows:

%ProgramFiles%\Microsoft Lync Server 2013\Deployment\Bootstrapper.exe

Update Commandlets !!

Also Grieg recommend running Update-CsAdminRole from Lync Management Shell to ensure any new commandlets are updated.

Improvements and fixes in the November 2016 update

This update improves the experience of moving users in a Lync Server 2013 environment.

For this point i cant find any information on what this means or brings to the Lync Server 2013.

Fix and Improvement Symptom / Cause
I cant find any information to say what this at all.
You cannot see a user’s telephone number (work number) on contact card through a Microsoft Skype for Business mobile client that connects to Microsoft Lync Server 2013.

Note This issue doesn’t occur in desktop versions of Skype for Business.

Assume that you have the Lync Mac Meeting add-in enabled in Microsoft Outlook for Mac. When you click an online meeting link in Outlook, Safari or Firefox is started. Then, you click Join using Lync for Mac or Communicator for Mac, Skype for Business for Mac opens, and you receive the following error message:

You’re not setup to join Skype for Business Meeting.

Consider the following scenario in a Microsoft Lync Server 2013 environment:

  • You’re using an Apple iPhone or Apple iPad that’s running Apple iOS 10.0.
  • You have Microsoft Skype for Business 2015, Lync 2013, or Lync 2010 installed on the device.
  • You try to join a meeting from outside the Skype for Business or Lync app. For example, you tap the Join Meeting link in an email message or calendar appointment in an app other than Skype for Business or Lync.

In this scenario, the device tries to start the desktop version of the website instead of the mobile version. The desktop version won’t try to start the app. Therefore, you can’t join the meeting.
Note The mobile version would try to start the Skype for Business or Lync app and join the meeting, or redirect you to the app store if it can’t join the meeting.

There’s an update for UCMA 4.0 run time –

This notes a Restart of the computer is required.

Restart requirement

You must restart the computer after you apply this cumulative update.


When installing i did get prompted to restart



There seems to be quite a few components that require updating with November 2016 CU Update.
