Access and Share External Microsoft and Google Files

If Salesforce Files Connect is set up for your organization, your mobile users can get more business-critical content at their fingertips. With version 7.3 of the Salesforce1 for iOS downloadable app, users can seamlessly access files in Microsoft SharePoint, OneDrive for Business, and Google Drive. Access to external data sources was previously available in the Salesforce1 mobile browser app only.
Files Connect available in: Enterprise, Performance, Unlimited, and Developer Editions

When browsing the Files list, attaching files to records, or sharing files with groups or in the feed, users can access external files just as they do files stored in Salesforce. Relevant external files appear in the Files list when these filters are applied: Recent, Owned by Me, Shared with Me, or Following. If the Files list is collapsed, an External section lets users navigate directly to outside files.

External file sources are included in the Files list if your organization has Files Connect set up and you have connected file sources. See Access and Share External Microsoft and Google Files for more details.
