Dear Microsoft Certification Support Team,
I am writing to request assistance regarding my Microsoft PL-400: Power Platform Developer exam, which was originally scheduled for 8 October 2026 at 12:00 PM.
Unfortunately, the exam could not be delivered on the scheduled date due to a technical issue at the Pearson VUE test center. The test center reported the incident to Pearson VUE, and the issue was recorded under Case ID 42753439.
Following the incident, I received an email from Pearson VUE confirming that the test center was unable to deliver my exam and advising me to contact Customer Service to reschedule. The email also confirmed that my exam voucher is valid until 13 February 2027.
However, when I attempted to reschedule the exam, I discovered that the voucher was no longer available/valid for me to use for the new booking.
I subsequently contacted the test center regarding the issue. I was informed that the Pearson VUE case had already been closed and that I should be able to reschedule because the voucher is still valid. As I am currently unable to use the voucher to reschedule, I was advised to contact Microsoft Support for further assistance.
I would therefore appreciate your help in reviewing my exam record and restoring/reactivating the voucher or providing the necessary authorization so that I can reschedule my PL-400 exam.
For reference:
I can provide the email received from Pearson VUE as supporting evidence if required.
I would greatly appreciate your assistance in resolving this issue and enabling me to reschedule the examination.
Kind regards, Abdullahi Ibrahim
