Using this db over a web based connection is just asking for trouble. I'd rather risk sharing an unsplit db over a network before I'd connect one to a back end on One Drive. Such drives are for storage, not for actively writing to like a db does. Heck, I might even use a thumb drive over the OP's method - and I basically wouldn't want to do either of the latter with my own db.
The more we hear silence, the more we begin to think about our value in this universe.
