Для тех, у кого медленный интернет или еще какая беда - оказывается, тут случилось большое горе у одного узконишевого продукта(ТМ):
Today we are announcing an update to our support policy for Windows Server 2016 and Exchange Server 2016. At this time we do not recommend customers install the Exchange Edge role on Windows Server 2016. We also do not recommend customers enable antispam agents on the Exchange Mailbox role on Windows Server 2016 as outlined in Enable antispam functionality on Mailbox servers.
