Why is it that for this blog post and others like the Exchange 2019 preview announcement that people are forced to ask obvious questions that should have been answered in the blog post itself?
You can't be bothered to take a few minutes to come up with a chart that will answer concerns about different OS and Exchange combinations and KB2565063?
You cant be bothered to offer basic information that people need to know about the Exchange 2019 preview in that blog post - we have to post basic questions there to get the information?
You cant be bothered to update the supportability matrix with things like information about support for the presence of Windows 2019 domain controllers ? https://docs.microsoft.com/en-us/exchange/exchange-server-supportability-matrix-exchange-2013-help
You cant be bothered to post something about the next Cumulative Updates in September when people are expecting it? Someone has to ask an obvious question about it in mid-October to get any information?
