Unable to complete Azure for Students verification - Unregistered email domain

Hi,

I am trying to sign up for Azure for Students, but I am stuck at the academic verification step.

When I enter my university email, I do not receive a verification email. Instead, I get the following error message:

"Your email domain is not currently registered with us. You can choose another verification method."

The issue is that there are no alternative verification options available on the page, so I am unable to proceed any further.

How can I get my institution's email domain reviewed/registered, or use an alternative verification method (such as manual document submission) to complete the verification?

Any guidance would be greatly appreciated. Thanks!
