Search the registry using the name of the OneDrive name listed in Windows Explorer you wish to remove. Delete the particular registry entries from the left section to delete the associated details. You should see your other accounts listed as well. Be careful to delete ONLY the associated OneDrive account. When I searched through my registry, I deleted about 6 entries and one couldn't be deleted. Once I finished, I no longer had the annoying OneDrive account associated to my old workplace.
