The Vorsite Cloud Backup service treats every Office 365 tenant as a unique end-customer subscription. The cost per seat for each seat is US$6 per month.
- Exchange Online: Each individual mailbox, shared mailbox and public folder under a tenant subscription counts as a seat.
- SharePoint and OneDrive for Business: Each user licensed to use SharePoint (includes OneDrive for Business accounts) under a tenant subscription counts as a seat. A licensed SharePoint user is defined as any user that is both licensed for SharePoint and has it enabled. Users can be enabled or disabled through the O365 admin portal.
