Build 2016: Office Developer Platform + Skype for Business API

#Build2016 for Office Developers – What’s New?

What’s new at Build 2016 for Office Developers (link)

Skype/Lync: This Operating System is not Supported by this Application

Office 2013 Pro with Lync 2013 RTM is installed on a new Windows 10 desktop machine. As soon as you click a Lync or Skype for Business meeting invite URI, an error keeps appearing:


This operating system is not supported by this application.

[ OK ]

Despite having restarted the Lync application follow by reboot of the machine, the same error appears. It is getting late and you are not able to join the meeting. What can you do?

– append ?sl= to the meeting URI to join using the Lync/Skype Web App.

– first start one of the Office applications like Word to allow setup to complete the final installation steps.

Skype for Business: Connection Successful … Error Pre-login Handshake … Timed Out

The error below could result when performing an administrative task with the Skype for Business Control Panel or running a cmdlet in the management shell.

PS C:\Users\administrator> Get-CsUser user01
Get-CsUser : A connection was successfully established with the server, but
then an error occurred during the pre-login handshake. (provider: SSL Provider, error: 0 – The wait operation timed out.)
At line:1 char:1
+ Get-CsUser user01
+ ~~~~~~~~~~~~~~~~~
+ CategoryInfo : NotSpecified: (:) [Get-CsUser], SqlConnectionExc
+ FullyQualifiedErrorId : Microsoft.Rtc.Common.Data.SqlConnectionException

To resolve, ensure that the host machine has sufficient RAM memory and/or close unneeded running applications. This fix applies even if the Windows operating system appears to be running with adequate memory. Otherwise, a machine reboot may be in order.

Skype for Business: A network-related or instance-specific SQL error #26 … 2/2

One workaround for this strange issue is to explicitly detach from and rejoin the member server FE01 to the AD domain. This should automatically fix the network category of the active network adapter* to “Domain network”.

Lastly, consider running nltest.exe with the /SC_QUERY and /SC_VERIFY switches to verify successful connection to the Active Directory network.
