The "Unexpected error" during AZ-104 exam scheduling is typically a platform or account issue on the exam provider side, not a problem with the AZ-104 exam itself.
Based on similar reported issues, the most common causes and next steps are:
- If the error appears right after entering address/payment details:
- There may be an account block at Pearson VUE (often due to multiple failed payment attempts). In such cases, the block must be removed by Pearson VUE support before scheduling will work again.
- If the error persists after multiple attempts or different browsers/networks:
- Direct support from the certification/exam support channels is required; it cannot be fixed from the user side alone.
Recommended actions:
- Contact Pearson VUE support
- Use the Pearson VUE support links provided under Microsoft certification support channels to check whether the account is blocked and have them remove any
ERROR_VUE_WIDE_BLOCKor similar restrictions.
- Use the Pearson VUE support links provided under Microsoft certification support channels to check whether the account is blocked and have them remove any
- Contact Microsoft Certification / Credentials Support
- Go to the Microsoft Certification Support / Credentials Support entry point (for example, via https://aka.ms/CertificationSupport or https://aka.ms/credentialssupport as referenced in the documentation).
- Sign in with the same Microsoft account used for scheduling exams.
- Open a support case under Product Family: Learning / Service: Microsoft Credential and describe the exact error text and when it appears.
- Support can verify eligibility, account status, and any backend issues with the scheduling system.
- If the error is tied to a specific offer or free-exam campaign (Ignite/Build/Cloud Skills Challenge):
- Use the dedicated Microsoft Certification Support forum links referenced for those offers to get help with discount/eligibility-related scheduling errors. A moderator will typically respond within one business day.
Until Pearson VUE and/or Microsoft Certification Support clear any account or offer-related issues, the scheduling portal will continue to show the generic "Unexpected error" message.
