Hi Atul,
Thank you for contacting the Microsoft community.
Being unable to schedule or access your exam certainly is not an experience we want you to have as I understand how important this is for you. Allow me to provide guidance and clarification with regards to this issue.
I appreciate you bringing this to our attention. We received several reports from other learners as well about the errors they are experiencing while trying to schedule exams. This was communicated to our support team immediately and we were advised that Pearson VUE experienced service interruption in registration and rescheduling over the last few days.
The announcement below was also made to notify other users about this and confirm that this issue has already been resolved.
I kindly request for your patience to try and schedule your exam and if the issue persists, please record a step-by-step screenshot using the Problem Steps Recorder (PSR) for Windows | Click this link if MAC device and share it with me along with the information requested through the private message I initiated.
This will allow us to investigate this issue further.
Thank you @H. for your valuable input.
Otherwise, if this solves your problem, please indicate “Yes” to the question and the thread will automatically be closed and locked. In case we do not receive a response, the thread will be closed and locked after one business day. Please be advised that after the case is locked, we will no longer be able to respond, even through private messages. If the resolution provided did not resolve the issue, please post a new question.
Sincerely,
