Intelligence Summary
Microsoft reminded organizations that ESU coverage for Exchange Server 2016 and 2019 will end in October. After that date, the company will stop providing security updates for these versions under the Extended Security Update program. This affects businesses that still run on Exchange 2016/2019 and rely on ESU to stay current. Without future patches, newly disclosed vulnerabilities will remain unaddressed. Admins should plan to migrate to a supported Exchange version or another email platform to reduce exposure.
Recommended Action
Review affected assets, schedule urgent remediation, and monitor related indicators.
