Jesper_Lerch yes cu re installation
don’t work my case ☹️
We have tried all the steps. I think we have a "multi - problem" here. Also reinstalled the CU20 several times without Sec. patch. Exchange services are all running. Fortunately it is only for the Hybird scenario and internal relay. Smtp even works but no powershell no single web service. What sequence in the individual steps would you suggest here 1 CU20 new without sec patch. 2. try to fix 2012
HTTP 500. does this also apply to the powershell not working. hmmmm I have also patched 10 exchange environments not a single problem. Have a nice weekend. Hope i get this server running again don't want a recovery installation or new one.
