Office versions - MSI and C2R

[Lotte Rose Nielsen]

Hi,

In my organization some users have Office C2R and others have MSI (Office 2016 ProPlus).

Is there a way to see if the current build of the MSI is a match to the current version of C2R?

I cannot figure out how to accurately compare these since C2R is at version 18xx and the MSI is version 16 build 16.0.4738.1000. 
Are these two a match, or do they differ in how many features they've received in the updates?

I think is not as easy as compare versions because Office 365 ProPlus is getting updated by the update cadence defined by your Office 365 admin....however, the "MSI" versión is not updated in the same way so basically any new stuff added by Microsoft to Office 365 ProPlus is not going to be in the "MSI" version...by the way: where did you get the MSI version of Office 2016? I though no matter if you are installing the Cloud version of Office or a Volume Licensing one, the installation mode is C2R for both
