Hello everyone, I hope you might be able to help with this CU23 update.
We use configuration manager for patching. CU23 was installing on my Exch2016 server in software center so I left it for 30 mins and when I came back software center had crashed and would not open. I had no visability of where the update was at so I looked in add remove programs and it said the update had installed. I uninstalled the config manager client and rebooted the server. I then re-installed the config manger client and opened up software center and no updates were pending so all looked good. I then noticed all the exchange services were all in the disabled state. So it looked like a failed install so I download CU23 from the update cataloge and tried installing it manually but this failed.
I then started all the exchange services and ran the exchange health checker and get the below errors
OWA and the ECP throws errors now. It is safe to try and uninstall the update from add remove programs ? Has anyone had a failed CU23 update ? I need to get the server back up and running.
Thanks very much
Steve
