Mark your calendars: On October 14, 2025, Exchange Server 2016 and 2019 will reach the end of support. After this date, Microsoft will no longer provide:
?? Technical support
?? Bug fixes
?? Security updates
?? Time zone updates
To avoid risks, we recommend migrating to Exchange Online or preparing to upgrade to Exchange Server Subscription Edition (SE), launching in early H2 2025.
Stay ahead and secure your organization’s communication infrastructure.
