No reply from support on my case

Hi JillArmourMicrosoft 

So, finally had the time to come back here ^^

I would like to thanks you for your help and follow up regarding this case.
Support finally contacted me to explain there was a huge backlog so I was not contacted in time.

Unfortunately, I learned that, for a case opened by a partner, the Operating System must be in mainstream support, not in extended support, which is the situation for Windows Server 2019.

I was able to work on the issue with a great engineer who guided me through several checks and we agree on a plan to upgrade the servers in WS2022.

If the issue is coming back, I will then open a new case 

Have a great day and thanks again ;-)

Gerald
