I think the external issues some folks are having including myself have to deal with the speed in which OneDrive starts relative to the external HD on Macs with multiple users when someone logs in. During the login, OneDrive starts immediately and if it fails to find the external location it will complain. Most external drives have to spin up or wake up and apparently its slower than the boot startup for one drive.
