Error While Proceeding to Pearson VUE Portal During Exam Registration

The “Unexpected error” page during exam scheduling/purchase is commonly caused by a Pearson VUE account block (often after multiple failed payment attempts).

Follow these steps:

1. Verify it is not a profile issue
   • Ensure sign-in is with the intended Microsoft Learn profile.
   • Confirm the Learn profile has a legal name and required contact details, as these are needed before redirecting to Pearson VUE.
   • Retry scheduling the AZ-900 exam from the official exam details page and select Pearson VUE as the delivery provider, as described in the step-by-step registration instructions.
2. Check for Pearson VUE account block (ERROR_VUE_WIDE_BLOCK)
   • When the “Unexpected error” appears, look at the browser’s address bar. If ERROR_VUE_WIDE_BLOCK appears in the URL, the Pearson VUE account has likely been blocked due to payment issues.
   • In this case, the block must be removed by Pearson VUE support; it cannot be fixed from Microsoft Learn.
3. Contact support
   • If ERROR_VUE_WIDE_BLOCK (or a similar Pearson VUE error) is present, contact Pearson VUE support using the link provided on the Microsoft Certification Support page at https://aka.ms/CertificationSupport so they can lift the block.
   • If no Pearson VUE block is indicated, or if the issue persists after Pearson VUE confirms the account is clear, open a case with Microsoft Certification Support from the same page so a moderator can review the Learn/registration side.

Once Pearson VUE clears any block and profile details are correct, retry the AZ-900 scheduling flow from the exam page; the purchase should complete without the “Unexpected error.”
