Outlook returns conflicting version numbers. What is going on.

Question

I am struggling with version numbers. My version of Outlook says it is "Version 2019 Build 14430.20174 (Click to run)".
However, in Outlook's VBA IDE Outlook._Application.Version gives 16.0.0.14430.

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.

Answer 1

Use

Application.Version

to the get Version of the Office Application.

Office 2010 was 14.0
Office 2013 was 15.0
Everything since then has been 16.0

Answer 2

Thanks Doug and John
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 16.0.0.14430.

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

Answer 3

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