As a user, probably one day you would ask this question to yourself, so I will explain how to know which version of OneDrive 4 Business you’re running.
First of all, you will need to go to “C:Program FilesMicrosoft OfficerootOffice16”
Take into account that the directory will change in case you are using the 32 bit version or if you have installed the SO in another language.
Try to locate the Groove.exe application, right click and select properties, navigate to details tab and you will see there the version you’re running:
Also is it possible to do this by clicking Crtl+Shift+Esc, go to Details tab, click on Groove.exe, right click, Properties, details and you will see the same version as showed before. And then… compare if it the last version or if you need to update the client
Hope it helps!
