We will maintain the current support dates for Exchange Server 2013, Exchange Server 2016, and Exchange Server 2019 however, we plan to support the next version of Exchange Server beyond October 14, 2025. We will provide more details on naming, features, requirements, and pricing in the first half of 2024.

The next version will require Server and CAL licenses and will be accessible only to customers with Software Assurance, similar to the SharePoint Server and Project Server Subscription Editions. We have moved the release date for the next version of Exchange Server to the second half of 2025. We know that customers and partners have reasons to run Exchange Server, and we are committed to supporting them. We have made changes to our Exchange Server roadmap since our September 2020 announcement, and today we’re excited to share those updates with you. While we continue to focus on security, we are now also ready to share our long-term roadmap for Exchange Server. Individuals across the globe can now receive monetary rewards for submitting security vulnerabilities found in Exchange Server, as detailed on the program web site. We strongly believe that close partnerships with security researchers help make customers more secure, so we also launched a security vulnerability bounty program for Exchange Server and other Office Server products via the Microsoft Applications and On-Premises Servers Bounty Program. We also updated our SU packaging to make installing SUs easier. We added AMSI integration in the June 2021 Cumulative Update (CU), enabled the Hybrid Management PowerShell module to work with MFA-enabled admin accounts, and released Security Updates (SUs) in April, May, July, October, and November of 2021, and in January, March and May of this year. We quickly responded to protect our customers, releasing out-of-band security updates, along with a one-click mitigation tool that later became part of Exchange Server as the Emergency Mitigation Service. In March 2021, we confronted a serious reality: state sponsored threat actors were targeting on-premises Exchange servers. Unfortunately, 2021 had other plans for Exchange Server. In September 2020, we announced that the next version of Exchange Server would be available in the second half of 2021 via a subscription model and that it would include support, product updates, security updates, and time zone updates.
