My problem: I have a one drive too small for my needs. I need 2.83 TB not 1 TB. So it does not back up all my files, but it stops me from backing up on a 5TB external drive by saying I need more TB on One drive! That is annoying. Stop synch does not work to solve it. There seems no solution to it. I hate One drive and the next computer I buy will be a Mac. Even if it is less versatile there's none of this nonsense.
