Whenever I try to sign in to the Azure Sandbox, this message will be shown in the popup:
Selected user account does not exist in tenant 'Microsoft Services' and cannot access the application '18fbca16-2224-45f6-85b0-f7bf2b39b3f3' in that tenant. The account needs to be added as an external user in the tenant first. Please use a different account.

For context, when applying for Azure, I opt for Azure for Students option. I registered with my personal account with verification to my education account. Now, in my Azure Portal there are 3 directories: DEFAULT, MICROSOFT LEARNING, and my School Name.
