Hi Mohd,
Thank you for contacting the Microsoft Community.
I understand that you were unable to take your AZ-900 exam after replacing the laptop as requested by the proctor. Allow me to direct you to the correct support team to assist you with rescheduling.
Since you encountered the technical issues with the access code, I highly suggest contacting the exam delivery provider, as any technical issues before, during, and after the online exam should be reported to them along with the details of your experience. This will help their team take proper action and give you further instructions on how you can successfully take the exam again.
If needed, they can also assist you with rescheduling your appointment to your preferred date and time, as their team has visibility into the available dates and slots. Kindly visit Pearson Vue's support page and select the region of your location for the direct contact number:
In case you need help with Microsoft Certification profile access/benefits and exam registration in the future, you can always post a new question so our team can give immediate assistance.
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. If the resolution provided did not resolve the issue, please post a new question.
