Attempting to enter Hotmail using brute force would have really bad consequences. You could at the very worst face jail time and at the least have your IP address targeted and no longer be able to use Hotmail or any other Microsoft product. Additionally, it is unethical to get into someone else's mail box without their permission. Yahoo also has software that will block your IP address if you
