Microsoft announce that when Exchange Server SE and Skype for Business Server SE become available in July 2025 there will be some price increases. These two products, along with SharePoint Server SE will increase by 10%, and the Core CAL Suite and Enterprise CAL Suite will increase by 15% and 20% respectively.

Microsoft confirm (May 2024) that the next version of Exchange Server will be a Subscription Edition (SE) which will be available early in the third quarter of 2025. From a licensing perspective it will follow the same rules as for SharePoint Server SE: you’ll need active SA to use the product – or buy the subscription licences – and if the SA lapses, then you retain rights to the 2019 version of the product.
