You can leverage other storage options, such as Box, even when you're already using Jive for SharePoint.
Using Jive for SharePoint with Box file storage
You can use Box file storage even when you're using SharePoint. After you've set up the
initial community connection to a Box account, connections between Box and Jive are set up group
by group. When you create a group, you decide whether the uploaded files will be synchronized
with Box. If you also use Jive for SharePoint, you can connect some groups to Box and some to
SharePoint. You can't connect the same group to both, however.
