Exchange Server 2019 cumulative updates after lifecycle

Question

Hello,

The primary end date for Exchange Server 2019 is January 9, 2024.

From this date onwards will Microsoft continue to release cumulative releases?.

Or we will have to think about switching to the new version when it is released in the second half of 2025.

Best regards.

Answer 2

Hi @Vicente Gallart | NUNSYS ,

According to the Microsoft Lifecycle Policy, Exchange Server 2019 follows the Fixed Lifecycle Policy .Mainstream support for Exchange Server 2019 will end on January 9, 2024, and extended support will end on October 14, 2025.During the mainstream support phase, Microsoft provides security updates, non-security updates, and new features and functionality for Exchange Server 2019. During the extended support phase, Microsoft only provides security updates for Exchange Server 2019.

Therefore, after January 9, 2024, Microsoft will no longer release cumulative updates for Exchange Server 2019 that include non-security fixes or new features. If you want to keep your Exchange Server environment up to date and secure, as mentioned in the aforementioned blog by Andy, it’s suggested to always keep your current Exchange 2019 servers up-to-date, and then upgrade to the next version of Exchange Server when it is released in the second half of 2025.
