Lê Thanh Tuấn I Hope you are doing well
Welcome to Microsoft Q&A Platform, thanks for posting your query here.
Based on the details shared, it could be possible that your school email address may not be eligible for the Azure for Students subscription.
Some possible reasons why your school email address may not be eligible include:
- Your school is not currently participating in the Azure for Students program.
- Your school email domain is not recognized as an eligible domain for this program.
- Your school email address may not be active or valid.
If your school email address is not eligible, you can try to use a personal email address to register for the Azure for Students subscription. You do need to use a school organization email for Azure for students. https://azure.microsoft.com/en-us/free/free-account-students-faq/
