User A is a Basic License holder. User B is a Business License holder. These two users, along with many additional users, are in the same organizational unit at the same company. When User A attempts to access Drive, they receive the following error: "We are sorry, but you do not have access to Google Docs Editors. Please contact your Organization Administrator for access." User B is not presented with the same error and accesses the service without issues.
How do you provide access to Drive for User A?
