Philipp,

Is your Exchange Server 2016 system virtualized? Have you checked memory and CPU consumption during CU setup?

Does the Exchange Server 2016 system have full access to the internet? If not, have you turned off the crl revocation check in IE?

It seems the problem solved it self. After waiting a long time I was able to click on install and the installation started. So let's see if the setup runns through.

  The update CU 10 run through with no other problems. After the setup all services were running and Exchange worked. However sending mails did not work. It took a restart and then around 10 minutes until the mail flow work correctly. There were some event log entries telling that transport did some forced configuration changes. Maybe this took a moment. I will observe some more, but Exchange seems to run fine now.
