Exchange Update CU 10 hangs after Readiness Check
We have Exchange 2016 running on CU 8 and would like to installe CU 10. Initially the readiness check showed different points, which we fixes. However no the setup hangs with readiness check at 100% ...
Looking forward to the results of the CU10 setup.

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.
