Editions supported: Offline Gmail is available for all Google Apps editions. However, the option to disable Offline Gmail for a domain is available only with Google Apps for Business and Education. (Compare editions.)

With Gmail Offline, users can access their mail and compose new messages when they don't have an Internet connection, or when their connection is unreliable or slow. When users reconnect, Gmail automatically sends any outbound messages.

Offline Gmail for your domain

In your Google Admin console, under Email settings, select Enable Offline Gmail for my users and click Save changes. (There may be a delay before the change takes effect.)

When you enable Offline Gmail, your users will see a new Offline tab in their Gmail settings.

Get your users started with Offline Gmail

Each user who wants to work offline must do the following to enable Offline Gmail:

1. Click the Settings link in the top-right corner of Gmail.
2. Click the Offline tab (available only if Offline is enabled for your domain).
3. Select Enable Offline Mail for this computer.
4. Click Save Changes and follow the directions from there. If your users don't have Gears installed, Gmail will help them install it. If they've previously installed Gears, they'll be prompted to allow Gmail to access Gears.

   Note: If your users are using Google Chrome, they won't be prompted to download or install Gears because it's already installed on the browser.
