As it is I am not sure how I can check a user's version number reliably. Can anyone explain the difference between the two different version numbers?
I always understood that the four components of a version number were Major.Minor.Build.Revision.

    What I was hoping for was some enlightenment on why the version numbers reported by Outlook > File > Office Account > About (Microsoft® Outlook® for Microsoft 365 MSO (Version 2109 Build 16.0.14430.20154) 32-bit ) while the version number reported by VBA is

    14430 is in both but in different positions. and 20154 is absent in the VBA version.

    16.0 is the only number that is of any consequence as far as VBA is concerned.
