Business Value

- Accelerated, document-centric processes across departments
The REWE Group has relied on SharePoint for years to support enterprise document management. The gap between Outlook and SharePoint remained a pain point because emails and attachments had to be stored locally before upload. In 2007 REWE launched a market evaluation, built prototypes, and assessed the Office 2 SharePoint (O2S) Outlook add-in. O2S has now been in place for more than a decade and closes the last mile between email and document filing.

O2S bridges SharePoint and Outlook
The add-in is used across all corporate headquarters departments and serves more than 3,500 daily users. Without O2S, staff must store messages locally before moving them into the right SharePoint library. With the plug-in, emails and attachments are dragged directly into the O2S menu and land in the correct SharePoint library immediately. Metadata is captured in the same step. Bernadette Griessler, IT Organiser for portal systems, notes: βThe seamless filing and easy metadata entry make O2S a well-accepted tool in our headquarters.β

Transfer emails, files, and folders via drag-and-drop
O2S moves complete folder structures via drag-and-drop. In the current release, O2S integrates with SharePoint as tightly as Exchange with Outlook. When a message opens in SharePoint, users enjoy the same capabilities they would expect inside Outlook, eliminating media breaks.
Minimal training required
O2S meets enterprise demands for configuration and administration. Many defaults are applied during installation, so users rarely need to adjust settings. Employees link their relevant SharePoint areas once inside O2S, and the connections remain available. The intuitive experience keeps training needs low and can be covered with a short eLearning module plus video tutorials.
