Microsoft to stop Exchange 2016 / 2019 security updates in October
July 21, 2026
Back to all postsMicrosoft has announced that it will discontinue security updates for Exchange Server 2016 and 2019 versions beginning October 2023. This means that these outdated systems will no longer receive critical patches, leaving them vulnerable to cyber threats and potential data breaches. Canadian businesses using Exchange Server 2016 or 2019 should take immediate action to upgrade or migrate to a more secure platform to protect their sensitive information and maintain compliance with industry standards. Failure to do so could result in costly data loss, reputation damage, and regulatory penalties.
