Spoiler Office 2019
Last year at Ignite, we announced Office 2019 – the next perpetual version of Office that includes apps (including Word, Excel, PowerPoint, and Outlook, and Skype for Business) and servers (including Exchange, SharePoint, and Skype for Business). Today we’re pleased to share the following updates:

• Office 2019 will ship in H2 of 2018. Previews of the new apps and servers will start shipping in the second quarter of 2018.
• Office 2019 apps will be supported on:
  • Any supported Windows 10 SAC release
  • Windows 10 Enterprise LTSC 2018
  • The next LTSC release of Windows Server
• The Office 2019 client apps will be released with Click-to-Run installation technology only. We will not provide MSI as a deployment methodology for Office 2019 clients. We will continue to provide MSI for Office Server products.

Activate RDS CAL 2019 on Windows Server 2016

Dear Microsoft Support,



We recently purchased Windows Server RDS CAL 2019.

When we tried to install Windows Server RDS CAL 2019 into Windows Server 2016, it shows the license is not recognized and couldn’t install.



My questions are :

1. Can’t Windows RDS CAL 2019 be installed in Windows Server 2016? If can, how?
2. Is there any way to downgrade RDS CAL from 2019 to 2016 version?

Thanks,
