Hello Sumaharika Peddireddy ,
Thanks for reaching out in the Microsoft Q&A!
To resolve the verification loop after adding your personal account as an owner to your Azure student account, first check your personal email, including spam folders, for a verification email from Microsoft. Contact your university's IT department to help complete the verification or regain access using your university credentials since you're graduating soon. If IT support isn't available, try logging into the Azure portal with your original university account. Avoid creating new support tickets if you can't access your university email. Additionally, set up an authenticator app for verification and update your security info with your personal contact details once access is regained.
