Hello Shun,
Greetings! Thanks for raising this question in Q&A forum.
No need to worry this is a very common situation and it can be sorted out! The message you're seeing "This email account has already been used for verification this year" appears because Azure for Students allows each school email address to be used for student verification only once every 12 months. So it's likely your email was used for a previous verification attempt at some point during the past year, even if you don't remember doing it.
Since you also can't access Azure Portal support (because you're not logged in with an active subscription), here's exactly how to get this resolved step by step:
1. Use the dedicated Azure for Students support form
This is the right path for you since you can't raise a ticket through the portal. Go directly to: 👉 https://aka.ms/azureforstudentssupport
This form does not require an active Azure subscription to submit anyone can use it.
2. Fill in the form with the following details
When submitting the form, make sure to include:
- Your full name
- The school email address you used for verification (the one that's blocked)
- A brief description of the issue mention that you received the error "This email account has already been used for verification this year" and that you believe this may be an error or a previous accidental attempt
- Your Microsoft account (personal email) that you want linked to the Azure for Students subscription
3. Check if your university email is already linked to a Microsoft account
Sometimes the verification was done on a different Microsoft account without realising it. Sign in at https://portal.azure.com using your school email address directly and check if there's already an Azure for Students subscription attached to it.
4. Wait for Microsoft's support team to respond
Once you submit the form, Microsoft's Azure for Students support team will review your case. They can manually reset or review the verification status for your school email. Response times are usually within 1–3 business days.
5. If you have a valid student ID, keep it ready
In some cases, the support team may ask you to verify your student status manually by sharing a copy of your student ID or enrollment letter. Having this ready will speed things up.
You're on the right track this just needs a quick review from Microsoft's side and it will be sorted out for you!
If this answer helps you kindly accept the answer which will help others who have similar questions.
Best Regards,
Jerald Felix.
