Como são atribuídas as licenças aos utilizadores?

Licenses are automatically assigned to invited users. The first goes to the user who installed the application. Each time this individual shares contacts with a new user, another license is allocated. When sharing with a domain group, each user in this group requires one license. 
If the number of users exceeds your available licenses, the additional users will be marked as “Unlicensed.” You can remove a user to transfer their license to someone else.
