I am running Server 2019 Core and Exchange 2019 CU8. I installed CU10 and all seemed to go well. I tried to install the SU and see no indication it actually installed. I am running powershell as administrator. I tried running just the name of the file and it went through the GUI and said it finished. I rebooted but running wmic qfe list does not show it listed as installed. So I ran the file with /qn switch and after a long time the server rebooted itself. wnic qfe still does not show it installed. Any clues to how to get it installed and how to verify it is installed? I did try the healthchecker script links in the previous posts but running it on my other box in the cluster it reports all up to date even though I have not even run CU10 in it yet, so I don't trust that script.
Thanks
