Lets find out exactly which Office bundle you have.
So start Office normally
Open an application, ie Excel
Go to File menu > Account command
On the right side it will display:
- the Office logo
- activation status
- full bundle name,
- icons for apps included in bundle
- below the "About" title it displays the Version and Build numbers
Give us all of that information. A screen cap may be easiest.
With that spreadsheet open do a File > Save As. Make note of the location it has been saved to. Click in the address bar at the top of the SAVE AS dialog and copy the path there. It will look something like this:
https://d.docs.live.net/e9a781234557256f/Public
If you paste that path into a new tab in your browser it will open up the appropriate onedrive folder. You can then delete the file.
