Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Hello Takumishin,
Since you have already attempted to contact the available support channels but have not yet been able to move forward, you may want to present the issue to your university IT administrator and ask whether they can investigate from the tenant side.
As your university account is managed within the school's Microsoft tenant, the IT team may be able to review configurations or restrictions that are not visible from your side.
Please ask them to verify:
- Whether your student account is currently active and eligible for Azure for Students.
- Whether there are any Conditional Access policies or tenant restrictions preventing access to Azure Education services.
- Whether your academic domain is properly enabled and recognized for Azure for Students.
When contacting them, I recommend providing the Error Code (53003), the date and time of the failed attempt, the Session ID, and any screenshots or diagnostic information available. This may help them determine whether the issue is related to your account eligibility or a configuration/restriction within the university tenant.
As you are experiencing this issue when accessing Microsoft_Azure_SupportPortalExtension with a live.com account, you may kindly ask your IT Admin to contact Azure Support on your behalf using their administrator account. This may help work around the issue and allow for further investigation.
Wish you all the best!
