Unable to schedule exama nd complete payment getting unexpected error

Contact Pearson VUE Support and ask them to check whether your Microsoft exam-registration account has a scheduling or finance block preventing payment for AB-410.

What to do

1. Open Microsoft’s Credentials support page and, under For Exam appointment and scheduling issues, select Pearson VUE Support.^1^
2. Start a support request or chat and provide:
   • Exam: AB-410: Building Intelligent Applications
   • The email address associated with your Microsoft Learn profile
   • The exact message: “We encountered an unexpected error”
   • The point at which it occurs—especially whether it appears before, during, or after payment
   • A screenshot showing the full error and browser address bar
   • The approximate date and time of the failed transaction
3. Specifically ask Pearson VUE to check for and remove any account-wide scheduling or finance block. In a closely matching case, a failed payment locked the candidate’s account; Pearson VUE unlocked it and scheduling then worked.^2^
4. Do not repeatedly submit payment while the status is unresolved. If a charge is pending or appears more than once, retain the transaction details and include them in the case.

AB-410 is the exam associated with the Microsoft Certified: Intelligent Applications Builder Associate certification.^3^

If Pearson VUE cannot resolve it

Submit a Microsoft Credentials Support request from the same Credentials support page:

1. Select online support request.
2. Confirm:
   • Product family: Learning
   • Product or Service: Microsoft Credentials
   • Type of Support: Professional No Charge
3. Choose Email, enter your location and time zone, and attach the screenshot.
4. Include your Learn username, Pearson VUE case number, exam code AB-410, and details of any failed or pending payment.

Microsoft states that Credentials Support is provided by email; selecting phone still results in email support.^1^
