Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Hello,
Microsoft does not have the authority to directly manage organization users. Instead, each organization's IT administrator is responsible for managing its users according to its internal protocols.
Have your son contact the college’s IT department. They setup and manage all the internal users. Microsoft does typically provide students Microsoft 365 licenses but they are awarded to the academic institutions and their IT departments will distribute them according to each of their own standards.
