Your mobile users' productivity doesn't have to stop when there's no connectivity. When you enable caching and Offline Edit for Salesforce1, users can keep working, unimpeded by a subway commute, FAA regulations, capricious cellular signals, or bunker-style buildings. Offline access is available for the Salesforce1 downloadable apps. The beta version of Offline Edit requires version 10.0 of the Salesforce1 for Android downloadable app or the Salesforce1 for iOS downloadable app.
Manage Salesforce1 caching and Offline Edit from Setup—enter Salesforce1 in the Quick Find box, then select Salesforce1 Offline.
