Hi, When I upgrade Exchange 2016 CU21 to CU22, I have error because KB2999226 is not installed. 138750-image.png
But Windows 2016 Server is not applied to this KB2999226.

Any idea for my upgrade ?

    I have updated Exchange 2016 on Windows 2016 and this update was not required. Sounds crazy but are you sure you are running W2016?
