Modern Authentication: Secure logon via MFA or certificate-based authentication currently requires a hybrid environment in which Azure AD provides these methods. Microsoft is therefore luring customers with exclusive innovations in Exchange 2019, which should bridge the long wait until 2025. In addition, its hardware requirements are significantly higher. However, updating to the 2019 version is not particularly attractive for most companies because support for this version ends at the same time as for Exchange 2016. Innovating Exchange 2019Įxchange 2016 users will have to take the intermediate step to upgrade to vNext via Exchange 2019. However, if you also have to upgrade Windows Server at the same time, then an in-place update for the OS on an Exchange machine will not be supported. Microsoft, meanwhile, is advertising that the move to vNext will be very easy because it can be installed via an in-place update over Exchange 2019. This leaves users with little opportunity to migrate to the new release. The plans for support seem half-baked because the lifetime for Exchange 2016/2019 expires as early as October 2025, and vNext won't hit the market until around that time. Hardly any transition period for migration This statement can also mean that Exchange vNext might be "vLast." The Modern Lifecycle Policy allows Microsoft to terminate support for a product within 12 months if there is no successor to it. Rather, according to the announcement, Exchange Server should simply be supported as long as there is substantial demand for the product. This does not specify an end date for support. New support policyĪ successor to vNext anytime soon is also unlikely because Microsoft is switching support for the new release to the Modern Lifecycle Policy. However, with seven years between the release of Exchange 2019 and vNext, customers are unlikely to see any upgrade after 2025 during the typical SA term of three years. The main benefit of this sort of maintenance contract is the right to all upgrades that appear during the term. In addition, however, they will have to sign up for a software assurance (SA). The subscription model is off the table instead, users will have to purchase server licenses and the required number of CALs, as usual. Microsoft also made a U-turn on the planned licensing of Exchange vNext.
