Customers can keep reading e-books they've already received on Microsoft Edge until early July. If you preordered e-books, your orders will be canceled.

Full refunds will also roll out automatically in early July, Microsoft said. Your e-books will be removed from Microsoft Edge in July when the company processes the refunds.
