If you use OneDrive for Business, you can cancel your subscription without affecting your data...as far as I know.
To do so, you must be a Global or Billing admin.
Find the subscription that you want to cancel, select the three dots (more actions), then select “Cancel subscription”. In the “Cancel subscription” pane, choose a reason why you are canceling and provide any feedback. Then select “Save”.
If you bought your subscription through a Microsoft representative or a reseller partner, you have seven days to cancel for a pro-rated refund. Contact your seller or partner to help you cancel your subscription.
