What’s New?

We have a pre-req!

“To apply this update, you must have Microsoft .NET Framework 4.5.2 (Offline Installer or Web Installer) installed.”

Some new commandlets have snuck in as well:

  • Get-CsAdditionalInternalDomain
  • New-CsAdditionalInternalDomain
  • Remove-CsAdditionalInternalDomain
  • – and no, in case you think I’ve missed it, there’s no “set-“

It doesn’t appear to have made its way into the online documentation or offline help yet, so for the time being it might have to remain a mystery…

Download

Installation

Here’s the “before” view of it going on to my Lab’s Standard Edition Front-End:

Reboot?

The installer didn’t prompt me to reboot, but I always like to give it one for good measure!

  1. I noticed for the download that it contains a “UcmaRuntime.msp” also this time. Do you know what is it used\needed for? Most CU’s only have the .exe installer, but this one has the msp file.

  2. Hello Greig

    Hopefully you can answer my questions.
    Our Skype for Business 2015 [CU4HF1] environment:
    2x EDGE, 3x Frontend, 1x SQL

    Do you recommend to install .Net Framework 4.6.2 or even 4.7? Because it is supported:

    Will CU6 fix the problem with the May 2017 .Net Framework security update?
    I mean, do i still have to request new Edge Internal and
    Frontend Pool Certificate with Client and Server Authentication to avoid this problem?

    So far I only installed all .Net Framwork security updates till April 2017

    Best regards,
