Setting up Gmail Offline

Google Apps administrators have two options for setting up Gmail Offline:
  • User installation: Allow users to download and install the web app from the Chrome store

    or

  • Admin installation: Use the Chrome MSI to deploy the web app on users' machines. This option is useful if you want to restrict user access to the Chrome Store, or manage the installation for users. Enable offline Gmail for your domain before following these instructions.
User Installation
  1. Enable Gmail Offline for your account
    In your Google Admin console, under Email settings, select Enable Gmail Offline for my users and click Save changes. (There may be a delay before the change takes effect.)

  2. Enable access to the Chrome Web Store. This can be configured per user organization. Follow the steps in the Help Center article and turn on Chrome Web Store service for your user organization.
Each user who wants to work offline must do the following to enable Gmail Offline:
  1. Use the current version of the Google Chrome web browser.
  1. Go to the Chrome Web Store to download and install the Chrome application for Gmail Offline.

The app will now appear on Chrome's New Tab page, and can be used immediately. Users can access the app in the New Tab page or add a shortcut (for Windows and Linux).

  2. Ensure users have the latest version of Chrome (13 or higher)
  3. Roll out Chrome policies to auto-install the Offline web app within Chrome.
    • On Windows:
      • The ADM/X templates for Chrome's group policy settings are here. They are useful for setting policies quickly, although editing the registry keys directly can work too.
      • Set the policy for the Extension Install Forcelist. More information about this policy is here. This setting should be set to: "ejidjjhkpiempkbhmpbfngldlkglhimk;https://clients2.google.com/service/update2/crx" in order to pre-install the Gmail Offline app.
    • On Mac:
      • The plist file is in the .dmg bundle. Download and open the bundle, find the resources folder and look for a file, "com.google.Chrome.manifest".
      • That manifest will have the Extension Install Forcelist setting. Set this to "ejidjjhkpiempkbhmpbfngldlkglhimk;https://clients2.google.com/service/update2/crx" to pre-install the Gmail offline app.
    • On Linux:
      • Follow the instructions for setting up Linux policy settings here.
      • Add a new setting called "ExtensionInstallForcelist" to your policy file with a value of "ejidjjhkpiempkbhmpbfngldlkglhimk;https://clients2.google.com/service/update2/crx" to get the Gmail offline app.
