Use the standard scheduling flow first, then apply the troubleshooting steps below.
- Confirm the normal scheduling steps
- Go to the Azure Fundamentals (AZ-900) exam page from the certifications or exam details page.
- Select Schedule with Pearson VUE in the Schedule exam section.
- Sign in with the Microsoft Learn profile (preferably a personal Microsoft account).
- Ensure the legal name in the Learn profile exactly matches the government ID; if missing, add it when prompted.
- Provide the required address, phone number, and contact email, then select Submit to be redirected to Pearson VUE and complete scheduling there.
- If an “unexpected error” appears at or after Submit
- This can be caused by an issue on the Pearson VUE side, including account blocks such as
ERROR_VUE_WIDE_BLOCK(often due to multiple failed payments). - If the error appears before reaching Pearson VUE, verify that all required profile fields (legal name, address, phone, email) are completed and correctly formatted, then retry.
- This can be caused by an issue on the Pearson VUE side, including account blocks such as
- Get targeted support
- For generic “unexpected error” issues where the page does not load or the voucher/payment step fails, use Microsoft Credentials support: https://learn.microsoft.com/en-us/credentials/support/help.
- If the error is related to a Pearson VUE block (for example,
ERROR_VUE_WIDE_BLOCK), contact Pearson VUE support using the link provided on https://aka.ms/CertificationSupport so they can review and lift any account block.
- If the issue persists
- Open a ticket through the Microsoft Certification Support channel described at https://aka.ms/credentialssupport so the certification support team can review the Learn profile and exam registration details.
These steps cover both profile-related issues on Microsoft Learn and account/payment-related issues on Pearson VUE, which are the most common causes of unexpected errors when scheduling exams such as Azure Fundamentals.
