@Solidlense You may reschedule the exam and here is the policy...
There is no charge if you reschedule an exam appointment at least 6 business days prior to your appointment. There is a fee of 12.5% (based on the current Microsoft exam price as published on Microsoft.com/learning) for rescheduling your appointment 5 business days or less before your exam date. If you fail to show up for your exam appointment (no-show) or dont reschedule your appointment at least 24 hours prior to your scheduled appointment, you forfeit your entire exam fee. Business days are Monday-Friday, not including holidays.
You may reschedule your appointment by calling the Pearson VUE call center, contacting the test center where your appointment is scheduled, or accessing the Microsoft Learning website and choosing the reschedule action. If you registered with accommodations, you must reschedule through the call center.
