Microsoft Extends Exchange Server 2016/2019 Support with Paid ESU Program (6-Month Lifeline)
Ddos 
Microsoft had previously announced the launch of a paid Extended Security Updates (ESU) program for Windows 10, allowing individuals, families, and enterprises to continue receiving security updates through a subscription-based model beyond the official end-of-support date.
However, Windows 10 is not the only product nearing its end-of-life in October 2025. Microsoft has also confirmed that support for Exchange Server 2016 and 2019—enterprise-grade email solutions—will cease in the same month, with no further security updates being released thereafter.
Recognizing that some organizations have yet to complete their migration, Microsoft has now introduced a paid ESU program specifically for Exchange Server. Unlike the three-year extension available for Windows 10, the ESU for Exchange is notably limited—offering a maximum of just six months of continued support.
In its official statement, Microsoft noted that while many customers have begun transitioning to the subscription-based Exchange (SE) edition, a brief extension in support is essential for those still finalizing their migration. These additional security updates will help ensure a smooth and secure transition.
Beginning August 1, 2025, customers can contact Microsoft Support to obtain detailed information regarding the ESU program for Exchange Server 2016 and 2019. Pricing is determined on a per-server basis and will be disclosed by the support team upon inquiry.
Once the ESU subscription is successfully acquired, Microsoft will provide comprehensive instructions on how to receive and apply the updates. This will enable organizations to continue receiving vital security patches for an additional six months, beginning in November 2025.
