IS EXCHANGE 2016 HYBRID STILL SUPPORTED?
IS EXCHANGE 2016 HYBRID STILL SUPPORTED as of January 2026?
Pls advise if this statement is correct:
Exchange Server 2016 was supported for hybrid deployments with Exchange Online, but as of October 14, 2025, it is no longer supported by Microsoft, meaning no security updates, bug fixes, or technical support are provided. While hybrid prerequisites still technically list Exchange 2016, running it now carries security and compliance risks, and Microsoft recommends upgrading to a supported version such as Exchange Server Subscription Edition or moving fully to Exchange Online. Continuing to use Exchange 2016 in hybrid is possible, but unsupported, so for a secure and compliant hybrid setup, an upgrade or migration is strongly advised.

Continuing to run Exchange 2016 in a hybrid environment after October 2025 introduces significant security and compliance risks. Organizations should carefully evaluate upgrading to Exchange Server Subscription Edition or fully migrating to Exchange Online to maintain support and security updates.
Exchange Server 2016 reached its end of support on October 14, 2025. As of January 2026, it is no longer supported for hybrid deployments with Exchange Online. Although Exchange 2016 can still operate in a hybrid configuration, Microsoft has ceased providing security updates, bug fixes, and technical support. Continued use therefore introduces significant compliance and security risks. To maintain a secure and supported hybrid environment, organizations are strongly advised to upgrade to Exchange Server Subscription Edition (SE) or transition fully to Exchange Online.
