Microsoft SharePoint Workspace, previously known as Microsoft Office Groove, is a desktop application designed for document collaboration in teams with members who are regularly off-line or who do not share the same network security clearance. Sharepoint Workspace has been replaced in preview versions of Office 2013 by Folder Sync functionality.
Groove's uses have included coordination between emergency relief agencies where different organizations do not share a common security infrastructure and where offline access is important, and amongst teams of knowledge workers, such as consultants who need to work securely on client sites. It is also used as a staging system for documents in development, where content can be developed then transferred to a portal when complete.
Groove was initially developed by Lotus Notes creator Ray Ozzie, and developed by Groove Networks of Beverly, Massachusetts until Microsoft's acquisition of Groove Networks in March 2005.
