To the extent permitted by law, the total liability of Microsoft, and your exclusive remedy, is limited to direct damages up to the amount you paid for the service in the 12 months before the claim arose or USD $100.00, whichever is greater.
For free service users, this cap means your maximum recovery is just $100 even if Microsoft causes significant harm such as a data breach, loss of important stored documents, or prolonged service outage that affects your business or personal life.
Microsoft's Services Agreement governs all major consumer Microsoft products and contains provisions that materially limit consumer rights, including mandatory arbitration and a class action waiver for US users, a broad content license that allows Microsoft to use anything you post or store, and a unilateral right to suspend or terminate accounts with limited notice. Consumers face significant data exposure through Microsoft's broad collection and use practices across services, and limited financial recourse given liability caps set at the amount paid in the prior 12 months. You can opt out of arbitration by mailing written notice to Microsoft Corporation, One Microsoft Way, Redmond, WA 98052 within 30 days of first accepting the agreement.
