If you live in the United States, you and Microsoft agree to binding individual arbitration before the American Arbitration Association (AAA) under the Federal Arbitration Act ("FAA"), and not to sue in court in front of a judge or jury. Instead, a single arbitrator will decide the dispute. Class action lawsuits, class-wide arbitrations, private attorney-general actions, and any other proceeding where someone acts in a representative capacity are not allowed.
This clause eliminates your ability to participate in class action lawsuits against Microsoft, which are often the only practical way individuals can challenge large corporations over small but widespread harms.
This agreement significantly affects consumers by requiring US-based users to resolve disputes through binding arbitration rather than in court unless they actively opt out within 30 days, eliminating class action rights for those who miss the deadline. Microsoft retains broad rights to modify, suspend, or terminate services and accounts without prior notice in many circumstances, and acquires a wide license to use content users submit through its services. You can opt out of the arbitration clause by sending a written notice to Microsoft Corporation, ATTN: CELA Arbitration Opt-Out, One Microsoft Way, Redmond, WA 98052 within 30 days of first accepting the agreement.
