Unable to Schedule AZ-900 Exam – Unexpected Error

Question

Hello Support Team,

I am trying to schedule the Microsoft Azure Fundamentals (AZ-900) certification exam through the Microsoft certification portal, but I am receiving the following error message during the booking process:

"Unexpected error. We encountered an unexpected error. Please try again later. If this issue continues, please contact site support."

I have already tried the following troubleshooting steps:

• Attempted booking in an incognito/private browser window
• Cleared browser cache and cookies
• Tried different browsers
• Logged out and logged back into my Microsoft Learn account

However, the issue persists and I am unable to proceed with scheduling the exam.

Could you please help investigate and resolve this issue so I can complete my exam booking?

Details:

• Exam: Microsoft Azure Fundamentals (AZ-900)
• Microsoft Learn account email: ******@gmail.com
• Country/Region: India
• Date attempted: Mar 30, 2026

Thank you for your assistance.

Regards, Gopala Krishna CherupallyHello Support Team,

Answer 1

Are you seeing ERROR_VUE_WIDE_BLOCK in the URL when you try and schedule the exam?

ERROR_VUE_WIDE_BLOCK is typically because your account has been blocked by Pearson Vue which normally happens because of multiple failed payments. You need to contact Pearson Vue support using the link on https://aka.ms/CertificationSupport to get the block lifted.

Answer 2

The described behavior matches known scheduling issues that must be handled by the exam delivery partner or Microsoft Credentials Support rather than through local troubleshooting.

Based on the provided guidance, take these actions:

1. If the error appears at the Pearson VUE step (after selecting exam, date, and time), contact Pearson VUE directly for appointment and scheduling issues. Use the Pearson VUE contact options listed under Exam appointment and scheduling issues so they can check for account blocks (for example, ERROR_VUE_WIDE_BLOCK due to prior failed payments) or other profile problems and clear them if needed.
2. If the error occurs earlier in the Microsoft Learn / Certification profile flow (before being redirected to Pearson VUE), open a case with Credentials Support so the support team can review the Microsoft Certification profile and fix any backend issues preventing scheduling.
3. If Pearson VUE confirms that the account is blocked (for example, because of multiple failed payment attempts), request that they remove the block; this is the documented resolution for that class of errors.

Do not keep retrying the booking flow until one of these support channels has reviewed and corrected the account or scheduling status.
