I am getting Unexpected error

Question

while trying to book for AI-900 exam it is showing Unexpected error.

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 "Unexpected error" when trying to book the AI-900 exam is commonly related to an issue on the Pearson VUE side, often tied to the exam account or payment history, not to Microsoft Edge or Windows 11.

Based on similar cases:

1. If there were multiple failed payment attempts previously, the Pearson VUE account may be blocked with an internal code like ERROR_VUE_WIDE_BLOCK. In that case, the block must be removed by Pearson VUE support before any new bookings can be made.
2. In other cases, moderators have confirmed that only Pearson VUE or Microsoft Certification Support can see and fix the underlying account issue.

Recommended steps:

1. Contact Pearson VUE support directly and explain that an "Unexpected error" appears when scheduling a Microsoft certification exam (AI-900). Ask them to check whether the account is blocked or otherwise restricted and to remove any block.
2. If needed, also open a ticket via Microsoft Certification Support using the guidance at https://aka.ms/CertificationSupport so they can review the certification profile and ensure it is correctly linked and in good standing.

Once Pearson VUE clears the account or resolves the error, retry scheduling the AI-900 exam.
