Hello PRATIK KHAJURE,
Thanks for your question.
To Reschedule or cancel your exam appointment via your Learn profile.
- Log in to your Learn profile and choose Profile from the dropdown menu in the photo avatar.
- Go to Credentials in the profile menu and select Certifications beside Applied Skills
- Scroll to the exam appointment you wish to cancel or reschedule and choose either the “Cancel” or “Reschedule” link.
- You will be redirected to the exam delivery provider’s site to cancel or reschedule your exam.
The above information is gotten from here: https://learn.microsoft.com/en-us/credentials/support/reschedule-and-cancellation-policy?source=recommendations
There is the possibility you may need further support regarding this and can't perform the steps above. I will recommend going to the Microsoft Training & Certification forums below:
