Systems powered by Microsoft’s Exchange Server 2019 will soon get an additional layer of protection, the company has announced. In a short update, Microsoft confirmed the imminent arrival of Windows Extended Protection (EP) on these servers. The feature will be turned on by default after the H2 2023 Cumulative Update (CU14) installs. IT teams that don’t feel this feature will be beneficial to them can opt out through the command-line CU installer, it was added. Extended Protection was added to the Exchange Server in August 2022. Back then, Microsoft told IT teams that for some vulnerabilities, the feature would need to be turned on. It later deployed a script that automatically turns EP on or off, and which worked even on subsequently updated endpoints. "We recommend that all customers enable EP in their environment. If your servers are running the August 2022 SU or later SU, then they already support EP," Microsoft said.
