If you have multiple OneDrive accounts, you can delete them all at once by going to the OneDrive website and clicking on the three lines in the top left corner of the screen. Then select “Delete account.” You will be asked to confirm deletion before it happens.
Sign in to your account from a computer browser, and click the Settings button. Click “Manage OneDrive”, and then select the account you want to delete. Click “Delete this account” at the bottom of the page, and then enter your Microsoft password to confirm deletion.
