Hi @Akshay A
Unfortunately, this appears to be a restriction of the AI Skills Fest 2026 voucher, rather than an issue with your AZ-104 appointment itself.
The voucher terms required you to schedule the exam by August 18, 2026, but you could take it as late as October 18, 2026. Similar candidates who booked before August 18 are now seeing the same “voucher expired” message when they try to reschedule after that date.
Since Pearson VUE has already confirmed they cannot override the voucher restriction, your remaining option is to contact Microsoft Credentials Support and ask them to review the voucher/appointment. This Microsoft Q&A forum is community-based, so contributors here cannot access your certification account, reset the voucher, or open a private account-verification session. Microsoft also directs certification support issues to Credentials Support.
One important point: don't cancel your September 19 appointment while you wait for a response, since cancellation could leave you unable to reuse the voucher after the August 18 scheduling deadline.
Also, for your privacy, I recommend removing the MS ID and order number from the public post and providing those only through the official support channel.
I hope Microsoft Credentials Support can review the specific voucher restriction for you.
