Just installed VBO v2 ... First of all, thanks for this release! Great product, great work! Really appreciated

Now I just come around with the question about licensing.
Currently we are moving User Mailboxes to O365. Not all of the users were migrated already.
Actually we have 72 Mailboxes in O365. Now VBO found some mailboxes from groups, that we have a total of 102 Mailboxes.
VBO found 208 Onedrives and 285 Sharepoint Sites.
In the licensing section it says: 208 licenses used.
How this will be licensed now? How do VBO count? What do I have to expect when people are adding more and more Sharepoint sites.... Are those counted as licenses?
Thanks for some clearup

Regards
Peter
