Question

Facing unexpected error while submitting credentials for booking PL300 exam

Answer 1

Dear @Shubham Deshpande,

I understand how frustrating it is to encounter a sudden roadblock while attempting to register for your PL-300 exam.

I noticed in the address bar of your screenshot that the URL ends with ERROR_VUE_WIDE_BLOCK. This specific code indicates that your testing profile has been automatically flagged or restricted on the backend by the exam provider, Pearson VUE.

Please be advised that Microsoft Certification, Exams, and Learn platform issues are not supported here in the Microsoft 365 Q&A forums. To get this resolved quickly so you can book your exam, please utilize the following dedicated resources:

Option 1: Contact Pearson VUE Directly (To lift the account block)

Since the block is on their system, you will need to ask them to review and remove the block from your profile.

• Pearson VUE Customer Service: https://home.pearsonvue.com/Test-takers/Customer-service.aspx
• Pearson VUE Live Chat: https://home.pearsonvue.com/microsoft/contact

Option 2: Reach Out to Microsoft Training Support

If you need a Microsoft moderator to assist with your profile or certification dashboard, you can post a question in their specialized support community. Click "Get Started" and then "Ask a Question" at the top of the page.

• Microsoft Training Support Forum: https://trainingsupport.microsoft.com/

I hope this directs you to the right team to get your exam scheduled quickly. Best of luck with your PL-300 certification.

Answer 2

The error shown in the screenshot corresponds to ERROR_VUE_WIDE_BLOCK, which indicates that the Pearson VUE account used to schedule the PL‑300 exam has been blocked, typically because of multiple failed payment attempts.

To resolve this and complete the booking:

1. Contact Pearson VUE support and request that the block on the account be reviewed and lifted.
2. After Pearson VUE removes the block, return to the PL‑300 exam scheduling page and submit the booking again.

If additional help is needed with Microsoft Credentials or scheduling after the Pearson VUE block is cleared, open a case with Credentials support.
