Support for Windows Server 2016? The TechNet page mentions it would be coming in CU5:


Edit: I guess the page does say "after CU5", so maybe no support yet.

Hi @Jeff Brown - stay tuned.  It's coming!  


Thank you for this update!  I was about to open a ticket and now I don't have to.


5. Fix move-csmeetingroom cmdlet for onprem->online move

@Earl Zirkle - Boom!

Is there an enhancement in this CU to enable the "Press 1" for the PSTN "call me at" feature in order to prevent getting voice mails on SfB conferences?  Rumor has it that was being released soon for on premise SfB 2015. Fingers crossed. 


Looks like Support for 2016 is included.  


Supports to use Windows 2016 as the operating system in Skype for Business Server 2015



@Deleted, unfortunately the support article was published prematurely. We will announce via blog as soon as Windows Server 2016 is supported.

The downloads are available. Is Skype for Business Server 2015 officially supported on Windows Server 2016 now?

Cumulative update adds supports for Windows Server 2016 to Skype for Business Server 2015




@Earl Zirkle -- Wanted to reach out to you.  How did moving your on-prem sfchub and/or SrS to Skype Online go when using the Move-CsMeetingRoom cmdlet?


Hello @David Christensen ,

We didn't use it.  We decided to use normal SfB accounts instead of meeting rooms.  It's working great for us so far.
