Work Folders on Windows Server 2012 R2 supports only local storage, i.e. the sync share location must be a local path on the server.
As we talked to customers, many of them use a NAS device for individual user data storage (e.g. home folders, user redirected folders), and they wish Work Folders can sync those data to user devices.
I'd like to recruit a few customers who are willing to collaborate closely with us on this feature development. If you are using offline files for user data which is stored by a NAS device, and migrate to Work Folders while keeping the data on the NAS devices, please share your contact info with me here:
