Thanks for reaching out.
I understand that you are facing issue while access Azure resources with your university account as you sign in in Microsoft Services tenant as a standard user with restricted access.
This error usually occurs when you sign in to Azure Portal using your personal account which is not added as an external/guest user to an Azure AD tenant.
You can ask the global administrator to invite you as a guest user as mentioned here: https://learn.microsoft.com/en-us/azure/active-directory/external-identities/add-users-administrator#add-guest-users-to-the-directory.
Once you are added to an azure tenant then you accept the invite sent to you via email, then you can also create your own tenant to have administrative access to perform all actions.
Thanks,
Shweta
