Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Thanks for the assitance, I have been in contact with Microsoft help desk. And they have said that If Microsoft's sign-in page specifically states that your email address is associated with "Konyang University" or directs you to a Konyang University organization during login, then the account association is most likely with that university's Microsoft tenant. In Microsoft , tenant names shown during sign-in are generally derived from the organization that owns the tenant.
Being based in the UK, this is going to be next to impossible to communicate the right message to have my email removed from their organisations tenant.
