Skype for Business Server 2015 & .NET Framework 4.6.2 Compatibility

Hello Everyone!

As we know, the .NET 4.6.1 Framework, which was released in spring 2016, is not supported to be installed on a server running a Skype for Business 2015 server role. With the new S4B Server update this February it is supported to deal with .NET 4.6.2 on a Skype for Business Server. Unfortunately, this fact is not shown in the list of improvements and fixes and this means that at the moment the updated statement of the NextHop Team is the only source of this useful fact.

Also the Technet article about the server requirements regarding the support of Windows Server 2016 as operation system has not been updated.…

Quickie: SefaUtil and Skype for Business Server 2015

This is just a short addition to my last post about SefaUtil.

At the moment there is no Resource Kit for Skype For Business Server. So for me this means the Lync 2013 ResKit should do the job until there is something new. Unfortunately SefaUtil from the Lync 2013 ResKit will not work properly with Skype for Business. SefaUtil requires UCMA 4.0, but Skype for Business uses UCMA 5.0.


There is a not supported workaround: Social Technet

I hope there will be a fix soon. It is rumored a fix will come with SfB CU1.



SEFAUtil is available for Skype for Business since 6/24/2015  – here.…

Migrate to Skype for Business 2015 – Part 2 – Perform the migration

There are a couple different ways to upgrade to Skype for Business Server 2015. In part 1 of this series we had a look at what these options are. Today we will actually go through the process of an In-Place upgrade. You can only use this method if you have a Lync Server 2013 deployment as a starting point. In this case I am using a Lync Server 2013 environment with one Standard Edition Front End.

This is a two part series of posts:

  • Part 1 – Your Options (this part focusses on the theory and your options from which you can choose for the migration)
  • Part 2 – Perform the Migration (this part takes a closer look into the actual steps you will perform while migrating)

For the upgrade we will follow these steps:


Step 1: Install Prerequisites

You want to start with installing the following prerequisites:

  • CU5 and latest hotfix for Lync Server 2013
  • Windows PowerShell 3.0 (at least build version 6.2.9200.0)
  • At least Microsoft SQL Server 2012 SP1
  • And also one of the following:

Also, you want to have 32 GB of free disk space before you start the upgrade.…

Migrate to Skype for Business 2015 – Part 1 – Your Options

If you are using Microsoft Lync Server and want to move on to Skype for Business 2015 you have a couple different ways to perform the migration depending on your starting point.


Note: I will be concentrating on the migration from Lync Server (2010/2013) to Skype for Business. If you are using the Office Communication Server (OCS) you should migrate to Lync Server first, before moving on to Skype for Business. You can also set up a new Skype for Business environment.

This will be a two part series of posts:

  • Part 1 – Your Options (this part will focus on the theory and your options from which you can choose for the migration)
  • Part 2 – Perform the Migration (this part will take a closer look into the actual steps you will perform while migrating)

So this part will cover options for migrating.…

The only supported operating systems for a clean installation of SfB Server 2015 are:

Changes in User Interface for Lync 2013/Skype for Business Client

A big step for the transition from Lync to Skype for Business (SfB) has been made. Along with the client update pushed out on April 14th comes the new Skype for Business user interface.

Continue using the Lync 2013 user interface

If you are using a Lync Server 2010/2013 the default user interface will be Lync. If the update is installed and you start your Lync/Skype for Business Client for the first time, you client will start in “Skype for Business Mode”.


After a successfull login the user is prompted that Skype for Business is available, but your admin either would like you to use Lync or it is not supported by your server.…
