Skype for Business Server 2015 – Windows Server 2016 and PowerShell 5.1 Support

Although Windows Server 2016 has been officially released since 26 Sep 2016 (Ignite conference in Atlanta), it is still not listed as a supported server operating system platform to install or operate Skype for Business Server 2015.  Likewise, this applies to domain controllers in the Active Directory environment.

Per “Server requirements for Skype for Business Server 2015” (TechNet – Topic Last Modified: 2017-02-23):

Windows Server 2016 is not included in this list right now, but we’re planning to add it as a supported option after Skype for Business Server Cumulative Update 5 is released. Until then, please don’t try to use Windows Server 2016 as an OS for your Skype for Business deployment today, as it’s not yet supported, and we don’t recommend it. And check back to this page once the cumulative update is released to confirm Windows Server 2016 is added to our supported list at that time.

Additionally, PowerShell 5.1 is delivered in Windows Server 2016 and Windows 10 Anniversary Update (Build 1607). On supported legacy and down-level Windows operating systems, you can apply Windows Management Framework 5.1 (KB3191565) to update to this current version. Nevertheless, WMF 5.1 is marked as incompatible with Skype for Business Server 2015 (or for that matter Lync Server 2013 and 2010).

The golden rule “If it ain’t broken, don’t fix it” should apply (particularly on live production systems)!

Skype for Business Online (Office 365): PowerShell Remoting Cannot bind -TargetServer

With Lync Server 2013 Administrative Tools (OCSCore.msi) locally installed, execution of the following remote PowerShell statement to connect to Skype for Business Online will trigger a prompt for TargetServer as shown:

$session = New-CsOnlineSession -Credential (Get-Credential)

cmdlet New-CsOnlineSession at command pipeline position 1
Supply values for the following parameters:
New-CsOnlineSession : Cannot bind argument to parameter ‘TargetServer’ because it is an empty string.
At line:1 char:12
+ $session = New-CsOnlineSession -Credential $credential
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : InvalidData: (:) [New-CsOnlineSession], ParameterBindingValidationException
+ FullyQualifiedErrorId : ParameterArgumentValidationErrorEmptyStringNotAllowed,New-CsOnlineSession


This happens even after you have installed the current version* of “Skype for Business Online, Windows PowerShell Module”.

To resolve this issue, make sure that you apply the latest version of Lync Server 2013 or patch/cumulative update described in KB2809243 over the out-dated version.

* version 9319.0 released 22 Jul 2015 as of this writing

Skype for Business Server and Flash Player (Desktop Experience)

If you do not want to inadvertently add Adobe Flash to your Skype for Business Server 2015 installation, a desktop application that serves no real purpose on your SERVER operating system (other than making it vulnerable from a security perspective), a review of my previous post* is in order.

This is important as various blog postings, including Microsoft’s #skype4b documentation on TechNet Library (link), continue to make the same (old) suggestion to install this “side application” as part of the prerequisites as of today.
