Having Mac synchronize files and folders with both iCloud AND OneDrive

Just got my first Mac.

Started manually moving files and folders from OneDrive to my Mac's iCloud.

To begin with I accessed my files and folders on OneDrive only, but realized that keeping it all on the Mac's iCloud makes more sense.

HOWEVER - as I have MS's Office 365 it would be awesome if I could synchronize my Mac with both iCloud and OneDrive.

Any advise?
