Exchange 2013 - Installing on Windows 2012. After installation, we are not able to install ANY of the CUs. Tried 1, 6-9, 23. I understand that the CU also is cross related to the .NET version. We have tried all of that. Should we be able to install CU23 without having any of the other CUs installed? Any assistance would be appreciated.
