About this tag
Exchange migration discussions on WindowsForum.com focus on the urgent need for organizations to move from on-premises Exchange Server 2016 and 2019, which reach end of support on October 14, 2025. Key migration paths include transitioning to Exchange Online or upgrading to Exchange Server Subscription Edition (SE). The U.S. NSA and CISA have issued warnings about imminent threats to on-premises Exchange servers, emphasizing the importance of hardening and migration. Microsoft has extended support through Extended Security Updates (ESU) until April 2026, but administrators are advised to act promptly. Topics also cover hybrid deployment strategies, security updates, and tools like Message Trace in Exchange Online for cloud mail management.
