This article defines the Enterprise Admin and the End Users, and the difference between the two.
Enterprise Admins
The Enterprise Admins (EA) are users who are allowed to login to ConnecttoTeams Enterprise Portal using their Microsoft Teams credentials. Within the Enterprise Portal, the Enterprise Admins can manage end users, configure services, and view reports.
The Enterprise Admin who can complete the registration of a Microsoft Teams organization in ConnecttoTeams should be a user who has a Global Admin access in Teams Admin Center. The Global Admin and other Teams users with delegated access (which are described here) can carry out various user management activities and other service configurations in the Enterprise Portal.
End Users
The end users of ConnecttoTeams are Microsoft Teams Users who actually use the various ConnecttoTeams communication apps within the Teams client.
