AgendaX licensing is based on the number of mailbox calendars that you display in the AgendaX Web interface. You can freely choose which mailboxes in your company you would like to display and which not. The total number of displayed mailboxes is the number of licenses you require. The AgendaX license is a onetime fee and includes patches and updates within the current version, as well as Standard e-mail support during the first 90 days. Additional Support options are available.
