How do I move my student subscription from school email registered account to my own email account?

Hi everyone,

I am new to Azure and need help configuring Microsoft Entra ID users, groups, and IAM roles for a university assignment.

My Azure for Students subscription is associated with my university’s tenant, where I am a standard user without permission to make the required directory changes. My instructor suggested creating a personal tenant and associating my existing student subscription with it using “Change directory.”

Here is what I have tried:

With my university account, the “Create” button under Microsoft Entra ID → Manage tenants is grayed out.

I registered for Azure using a personal Microsoft account. I initially received an AADSTS16000 error referencing the “Microsoft Services” tenant, but I can now access a directory labeled “Default Directory.”

When creating a new tenant from the personal account, the form requires a subscription and resource group. The Subscription dropdown is empty, so I cannot continue.

My main question is: Can I use the existing personal Default Directory and associate my Azure for Students subscription with it, rather than creating another tenant?

If so, how do I confirm my administrator permissions and complete the directory change when the original subscription and target directory are accessed through different accounts?

If a new tenant is necessary, what is the supported approach for an Azure for Students user without upgrading to a paid subscription?

I would like to retain my existing student subscription and credits. Thank you for your help!
