Work offline in the new Gmail
We can guarantee you’ll want to work on the go, but we can’t guarantee you’ll have Wi-Fi. Fortunately, native offline capabilities in the new Gmail make it possible to work without interruption—even when you don’t have an internet connection. Starting now, people using the new Gmail in a Chrome browser (v61 or higher) can search, write, delete, and archive up to 90 days of messages, even when they’re offline.
Enable Gmail offline for your domain
To get started, enable Gmail offline for your domain in the Admin console (the feature is disabled by default).
If you want offline content deleted for your users when they sign out of their Google accounts, check the Force deletion of offline data on log out of Google account box. This will prevent your users from keeping content on their local devices when they log out.
Turn on Gmail offline for your account
Once you’ve enabled Gmail offline for your domain, individuals who are using the new Gmail can turn it on from the Offline tab in their settings (the feature is disabled by default).
They can also choose whether to keep offline data on their computers or have it removed when they log out.
Uninstall the Gmail Offline Chrome app
We previously announced that we’re moving Chrome apps, like Gmail Offline, to the web. The Gmail Offline Chrome app will stop working in the future, so we recommend that users uninstall it and begin using the native offline feature as soon as possible.
Enable the new Gmail
These new native offline capabilities are only available to customers participating in the new Gmail Early Adopter Program (EAP). To opt in to the EAP and enable the new Gmail for your domain, follow the instructions in the Help Center.
