I couldn’t log in to my AZ-900 exam due to a backend issue, and the exam code expired.

Question

I was unable to log in to my AZ-900 exam due to a backend issue. When I attempted to access the test, it showed that my exam code had expired, and I am now unable to reattempt the exam. Could you please guide me on how to reschedule it?

Answer 1

Greetings!

This is Tin, I'm so sorry to hear about what happened. Microsoft policy allows rescheduling up to 24 hours before the exam but since you had a system error, a support can investigate it and check to reschedule it.

You can contact the Pearson VUE Support - https://home.pearsonvue.com/microsoft/contact

Or Certiport Support

Thank you,

Tin

Rescheduling must be done through the official exam channels; when an exam code or voucher is shown as expired, self-service rescheduling is usually no longer possible and direct support is required.

Use these steps:

1. Try rescheduling from the Learn profile
   • Sign in to the Learn profile.
   • Go to Profile → Credentials → Certifications.
   • Find the AZ-900 exam appointment and select Reschedule or Cancel.
   • This will redirect to the exam delivery provider (typically Pearson VUE) to complete rescheduling.
   • If the code/voucher is already marked as expired, this option may not be available or will fail.
2. If rescheduling fails because the code is expired
   • Contact Pearson VUE Support and provide:
     • Exam: AZ-900
     • Date/time of the original appointment
     • Description that login failed due to a backend issue and the code then showed as expired.
   • Pearson VUE can check the appointment status and, if appropriate, reinstate or replace the voucher/exam slot.
3. If Pearson VUE cannot resolve it
   • Open a ticket with Training, Certification, and Program Support and include:
     • Pearson VUE case number (if one was created)
     • Screenshots or details of the error and the expired code message
   • Support can investigate exam/voucher status and advise on reinstatement or next steps.

Key policy points from the context:

• Exam appointments must be rescheduled or cancelled at least 24 hours before the scheduled time; otherwise the fee or voucher is forfeited, and a no‑show may also forfeit a free-offer exam.
• If an exam is cancelled by Pearson VUE (for example, due to system issues on their side), vouchers are normally reinstated automatically and can be reused to schedule another exam.
• For technical issues during an exam that create a Pearson VUE case, it is possible to request special handling (for example, waiving waiting periods or addressing voucher status) through official support channels.

Because the failure was due to a backend issue and not a normal no‑show, resolution depends on Pearson VUE and Certification Support reviewing the case and, if they confirm the issue, restoring the ability to schedule AZ‑900.
