AZ900 Exam Schedule error

The “Unexpected error” at the Pearson VUE handoff page is commonly caused by an issue on the Pearson VUE side, often an account block after failed payment attempts.

Based on similar reported cases, the most effective next steps are:

1. Contact Pearson VUE support directly
   • This error frequently indicates ERROR_VUE_WIDE_BLOCK, which occurs when Pearson VUE has blocked the account (typically after multiple failed payments).
   • Only Pearson VUE support can confirm and remove this block.
   • Use the Pearson VUE contact options listed on the Microsoft Certification support pages (for example, via the link on https://aka.ms/CertificationSupport as referenced in the Q&A threads) and explain that you receive an “Unexpected error” immediately after submitting the address/phone page when scheduling AZ‑900.
2. If needed, open a Microsoft Credentials support case
   • If the issue persists after contacting Pearson VUE, open a case with Microsoft Credentials support so a moderator can review the certification profile and help coordinate with Pearson VUE if required: https://learn.microsoft.com/en-us/credentials/support/help.

Once Pearson VUE removes any block or resolves the account issue, the error should disappear and the AZ‑900 exam can be scheduled normally from the “Schedule exam” section of the AZ‑900 exam page.
