Hi Jonathan,
It seems that you are using Office 365 Education E3 trial plans for faculty and students. After verifying that your organization is an accredited academic institution, your organization can receive Office 365 Education E1 at no cost. As a result, I wonder if you have received the validation email. The customer will be able to see and purchase the Academic offers in their portal when the vanity domain is approved . If not, please provide us with your tenant information so we can check your subscriptions and the eligibility and help you better.
