Okay, let's assume we have a brand new, greenfield company that want to run Power BI Pro. They do not have (nor need) Office 365 but they do require all the Power BI Pro features, specifically (but not limited to) the 'Groups' functionality.
What's the minimum edition of Office 365 they need to purchase to support this scenario? If they buy Power BI Pro (for their organisation, not Individual) on it's own - will they have access to the Group functionality and other Pro features for the list price or will they need to pay an additional fee for Office 365 (or Sharepoint Online a-la-cart)?
Understanding the overall cost associated with this approach is the key here - is it just a Power BI Pro licence or a Power BI Pro plus an Office 365 licence to support all of the Pro functionality? If that latter, which minium (read cheapest) Office 365 Edition is the one I need??
Thanks
