Work offline in Gmail
Gmail offline is a feature of the Gmail Early Adopter Program (EAP). Before you can enable Gmail offline, you need to opt in to the Gmail EAP.
Even when internet access isn't available, you can read, write, search, delete, and label email messages using Gmail offline. Later, when a connection is available, Gmail automatically updates and sends messages in your outbox and downloads updates from the server. By default, Gmail stores the last 30 days of mail, including attachments. Spam and trash are not stored. To work offline in Gmail, you need the latest version of the Chrome browser, version 61 or later.
Note: Keep Gmail open in only one tab for offline capabilities to work properly.
Enable Gmail offline for your domain
As a G Suite administrator, you must enable offline capabilities for your domain before users can turn on Gmail offline in their Gmail settings. Gmail offline is off by default.
From the Admin console Home page, go to AppsG SuiteGmailUser settings.
- Scroll to Gmail web offline.
- Check the Enable Gmail web offline box.
- (Optional) If you want offline content deleted for all users when they sign out of their Google account, check the Force deletion of offline data on log out of Google account box. This prevents users from keeping content on their local devices.
- Click Save. It may take up to an hour for changes to propagate to all users.
Have users enable Gmail offline
Users who want to work offline need to enable Gmail offline individually in their Gmail settings.
From your inbox, choose Settings Settings.
- Click the Offline tab.
Check the Enable offline mail box.
Under Security, select one of the following to indicate how to handle offline content when you sign out of your Google account.
Keep offline data on my computer. Data stored on your device will not be deleted when signing out of your Google account or when changing your password. To delete account data from your device disable offline mail and save changes.
- Remove offline data from my computer. Data will need to be resynced to your computer when signing back into Google.com Mail. It may take a few hours to resync the mailbox.
Set Gmail offline preferences
By default, Gmail offline stores the latest 30 days of email and attachments on your local device, and Chrome allows Gmail to use up to 7% of your available hard drive space for offline content. To reduce the amount of storage space your offline content uses, uncheck the Download attachments box in Sync settings or reduce the storage duration to 7 days.
- In Gmail, click Settings Settings.
- Click the Offline tab.
- Choose a value in Sync settings.
Values are 7, 30, and 90 days.
- (Optional) Uncheck the Download attachments box.
- Save your changes.
Tip: To ensure that you’ll always be able to access Gmail offline services, keep a Gmail tab open, even when you shut down your computer.
Troubleshoot common issues
Take note of common issues you might experience while working in Gmail offline.
Offline capabilities stop working
- If a G Suite admin disables Gmail offline for a domain, it becomes unavailable to individual users, even if they've enabled it in their Gmail settings.
- Gmail offline services only work when Gmail is open in one tab. Check your browser tabs and close any additional tabs running Gmail.
Gmail won’t open or quits unexpectedly
If Gmail won’t load or stops working, try clearing your browsing history:
- From your Chrome browser, choose Chrome Clear Browsing Data.
- Check the Browsing history box and click Clear Data.
Gmail offline is out of storage space
If your mail contains a large number of attachments, uncheck the Download attachments box in Sync settings and reduce the storage duration to 7 days (see steps 1 through 5 above).
