Released: February 2023 Exchange Server Security Updates

PrayingMoses the fix that was delivered first time was a later version of the January 2023 SU. This SU updated the AdminDisplayVersion and therefore you see 2507.18. The server which shows 2507.17 had the January 2023 SU installed, and you installed then the "correct" February 2023 SU. This is to address the following issue:

Version error when you install Exchange Server in RecoverServer mode – going forward, February 2023 and newer SUs will not cause this issue (but modifications made by the January 2023 SU might still require manual action during a server recovery operation, so the steps outlined in the article might still apply with later SUs installed)

You can check the installed SU build number as described in option 2:
