Since we announced our transition to Prometric as our single exam delivery partner, we've been saying you could exchange any Pearson VUE exam vouchers you have sitting around for a Prometric voucher. That offer is still good until July 31 this year - so if you would like a replacement voucher contact mslvouch@microsoft.com (sooner than later). If you have any suggestions, compliments, or complaints about recent experiences with Prometric (voucher related or not), you are still encouraged to share them with our team.
