Check out our latest news - New cloud storage options for Office mobile and Office Online

We're looking for cloud storage providers interested in connecting their cloud storage services to Office for iOS and Office Online. Check out the Office for iOS and Office Online integration details and technical whitepapers available to learn more. Our team will add updates to this web page as we release more Office integration features.

Office for iOS

We're offering cloud storage providers the opportunity to integrate with Office for iOS. With this integration, the user will be able to add your cloud storage service as a "place" in Office, whereby the user can browse for PowerPoint, Word, and Excel files on your service right in Office itself. The user will be able to open, edit, and create against your service directly from within Office as well as open these files from your app into Office. Although currently the experience is limited to browse, open, save, and create, our intent is to include more robust scenarios in the future.

In order to integrate with Office for iOS, a third-party will have to implement the server side portion of the WOPI APIs as well as update its iOS app. WOPI is the same protocol needed for Office Online integration. To learn more about integrating with Office on iOS and to register for the program, please read the accompanying documentation and sign-up.

For integration on Android and Windows 10, see Document Picker.

Office Online

We're offering cloud storage providers the opportunity to integrate Office Online into their web-based experiences. With this integration, users will be able to view and edit PowerPoint, Word, and Excel documents stored in third-party cloud storage. This is a preview program aimed at delivering Office experiences where users need them. Currently the experience only allows for a single editor at a time; however, our intent is to work with partners to extend the scope of Office Online integration to include more robust scenarios around sharing and collaboration over time.

In order to integrate with Office Online, third-parties will have to implement the server side portion of the Office Online REST API (WOPI) as well as building the HTML and script necessary for hosting the Office Online experiences. To learn more about integrating with Office Online and to register for the preview program please read the accompanying documentation and sign-up.
