The ERROR_VUE_WIDE_BLOCK message when trying to schedule a Microsoft certification exam indicates that the Pearson VUE account used for exam delivery has been blocked, typically due to multiple failed payment attempts.
To resolve this, Pearson VUE support must remove the block. Use the Pearson VUE support contact path provided via Microsoft Certification Support and work with them to lift the restriction on the exam profile. Once the block is cleared, exam scheduling on the Microsoft site should work again.
