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. Note that the maximum sync period for data is 30 days.
Gmail Offline capability is provided as a free Chrome web application.
