Exchange Online Mail Flow Rules Move to New EAC

Microsoft is moving the creation and management of mail flow rules to the new EAC from November. The UX in the legacy EAC should disappear in December 2022. The new UX is prettier and works better (apart from the rule wizard), but it's a little disappointing that we have essentially the same way of managing mail flow rules in 2022 as we had in 2006. You can only hope that things might improve in the future.
