This problem CONSTANTLY haunts me and my customers. (1) Uninstall OneDrive (2) Reboot (3) Apply policy to block OneDrive reinstallation (linked below) (4) Attempt to change your folders with Explorer: right-click the library folder, then go to properties, Location, and choose Restore Default. If this fails, use Move. (5) Manually move any remaining files from c:\users\username\OneDrive (6) Open registry, manually edit the keys shown in the link (7) Delete leftover OneDrive folder (8) Reboot for completion!
