📅✨ Microsoft Exchange 2016 and 2019 to End Support in October 2025. Microsoft has announced that Exchange Server 2016 and 2019 will reach the end of extended support on October 14, 2025, following their mainstream support conclusion in October 2020 and January 2024, respectively. After this date, Microsoft will cease to provide technical support, security fixes, and time zone updates, potentially exposing users to security risks. The company recommends that administrators migrate to Exchange Online or prepare for an upgrade to Exchange Server Subscription Edition (SE), which will be available in early 2025. Detailed guidance for migration is available on Microsoft’s documentation site to assist global admins in transitioning to supported versions.
