The licensing for this works with your purchased Office 365 services. Users with Office 365 Business Premium, E3 or E5 CALs get the rights to Office applications on the desktop. The licenses are activated by users signing in to Office 365 applications with their Office 365 account. When you purchase Office 365 Business Premium, E3 or E5, this gives you access to Office ProPlus. It does not give you access to Visio or Project applications. For many organisations, they will continue with the licenses they already own under their EA for this pair. Being totally honest, the pricing for Visio and Project seem pretty steep.
