Hi Mohit,
Thank you for contacting the Microsoft Community.
I understand that you encounter technical issues launching your exam and I know how important it is for you to take your exam and display your proficiency. Let me provide additional information to regarding this matter.
For us to locate your account and check your exam status, kindly provide us with the requested information through the private message that I initiated.
If you encounter a technical issue during an exam, this incident should be reported immediately to Pearson VUE's Support Team. Usually, the proctor will try to reach out to you. If you haven't been contacted, it's crucial to report this immediately to Pearson VUE support for further assistance. Their team can take necessary steps and guide you on successfully retaking the exam. You can reach them using the link below:
Pearson Vue Support: https://home.pearsonvue.com/microsoft/contact (they typically respond within 3-5 business days)
Should you have required additional assistance after contacting Pearson Vue, kindly share the Case ID through the private message that I initiated. This will allow us to follow up on your case if you did not hear from them.
To avoid technical issues in the future, I highly recommend running a system test prior to the exam as well as consulting the OnVue Technical Requirements for the Candidate and reading the Microsoft Candidate Agreement.
I look forward to your response. Please note that if no response is received after two business days, the case will be closed and locked. After the case is locked, we will no longer be able to respond, even through Private Messages.
