Google Chat and Hangouts
Google provides three tools to allow you to work offline with Google Apps, each for use with its specific app. All work in the Chrome browser only. We've got instructions to assist you in implementing Offline Mail, Offline Calendar, and Offline Docs/Drive. We also have a few comments to help you get the most out of your offline experience.
More Google Products
Google has several other applications that we encourage you to use, but that we don't actively support. You can see them here.
Google Apps New user cheat sheet
Google has a page to help you get started with (or remind you about) Google Apps (mail, groups, drive, docs/sheets/slides/forms, calendar, hangouts) here. It even includes links to more detailed information.
Google Apps Marketplace
The Google Apps Marketplace includes applications that integrate directly with Google Apps.
