An important question for MS Exchange Server 2016 customers. Let's assume that tomorrow we buy the MS Exchange Server 2019 Standard under SA, as well as 200 User CALs Standard under SA and this in an Open Value contract over 3 years. With this type of license, am I automatically entitled to switch to MS Exchange SE from Q3-2025 OR do I need to purchase new licenses again? Because otherwise it will be very difficult to convert EX2016 customers in advance. Or in other words, is it possible to buy the SE licenses this year with the right to downgrade to EX2019? This should be communicated as soon as possible. And nobody can tell me that a 3 trillion company doesn't already know this today.
