Do Power BI Group Workspaces require a certain type of Office 365 License?

I have created a Group Workspace in Power BI, was able to add users to it, and more importantly we are all able to access the corresponding One Drive share which is created along with the Group Workspace. I did this where we had an Enterprise E3 account.  I tried to do the same thing at a site where they have several Office 365 Pro licenses.  When the One Drive share is created, there is no way to add files to it.  The one drive which is created does not show up under Business One Drive or any other place.  As a work around, I tried to create a separate group outside of Power BI, but I can't get Power BI to see that group. Why can't I access the One Drive which is created with the Group Workspace?

After talking to Microsoft I found out that access to Power BI Group Workspace One Drives require purchasing an Exchange 365 license.  I have discussed the topic in my blog  http://www.desertislesql.com/wordpress1/?p=799 and included the relevant links to Microsoft Licensing information.
