A while ago, I published an article about my experience with Exchange 2016 so far. Here is a minor update. Since my post, I found another Issue: The Exchange servers seemed to hand during a restart (reboot)!
We applied some patches on Monday and my two (2) servers hang during the restart. The RDP Session was terminated, but then nothing happened. I waited nearly an hour per node, but nothing happened. Even the local console (Via Hyper-V) was unresponsive. Only a hard Power Cycle fixed my issue.
The Patch was applied successful, so I decided to restart both nodes again today, but I had the same issue again.
