I did a AZ-900 course which qualified me to take the exam for free:
Once you have completed both Part 1 and Part 2 of this training, you are eligible to take the Microsoft Azure Fundamentals certification exam at no cost.
But when I follow the instructions, which is to sign up for the exam using the same email registered for the course, it gives me this error:
Please login with your personal Microsoft Account (eg: @hotmail.com) to create/edit your Microsoft Certification profile.
A colleague who did the course with me had the same issue. How are we supposed to redeem the free exam if we can't use the email address we signed up with?
