Box is now seamlessly integrated with Microsoft Office Online. This integration lets you create Microsoft Word, PowerPoint and Excel files in Box, edit them using the Office Online web applications, then save them directly back to Box without downloading additional programs or applications. In addition, the Office Online integration supports concurrent editing, so you and your coworkers can collaborate on documents in real-time.

There are slight feature differences between the Office programs installed on your PC and their Online counterparts.  This guide from Microsoft’s Knowledge Base outlines those differences.

Note: Because documents are automatically saved to Box, all of our data categorization rules (Data Categorization Table for Box) apply, so you can be assured that your data is safely stored on Box.

Box for Office Online now supports real-time co-authoring.
