I have a retail "WINDOWS SERVER 2016 RDS CAL5 USER" product key which I want to apply to a server 2012 standard RDS License server. The license is a retail pack purchased through Dell
I know that I need to downgrade the license by ringing the Microsoft Clearing House in the UK (02031474930) , providing them my license server ID and my product key. I have tried this process at least 10 times now. Every time i call I provide the details
to the agent over the phone, wait, they then tell me there was an error and connect me to the corporate licensing team. the corporate team then tell me they cannot help, they then usually either hang up, or transfer me back to the 1st team i spoke to, and
I go round and round in circles.
I have also tried entering the code into the 2012 licensing server, it tells me the license code is invalid.
I have tried entering the code into a 2016 licensing server (just to test) and it accepts the code, so I know the code is valid for RDS 2016.
Is anyone able to tell me
A. can i actually downgrade a retail "WINDOWS SERVER 2016 RDS CAL5 USER" for use with server 2012. my understanding was that all RDS CALs are backwards compatible but not forwards.
B. is there some specific alternative team at Microsoft that I should be dealing with?
Microsoft support over the phone have been utterly horrendous, nobody takes ownership and I am left going round in circles.
I have spoken to Dell who have tried to help, even to the point of conference calling Microsoft with me, they too were appalled at Microsoft's customer service.
Am I doing something wrong or do i just need Microsoft to take ownership and sort this out?
