While you can use your Gmail account offline almost like you would while online, there are a few features that aren’t yet available offline:

• Access to the Contact Manager
• Complete search results. Try your search again when you’re back online for more results.
• Access to conversations in Spam and Trash
• Some Gmail Labs features

If you encounter a problem with offline access, you can use our troubleshooting tips in the Settings page in Gmail.

***Special Note: The following is a known issue with multiple users using offline on the same browser. We're working on fixing it and don't need further reports.***

- If you've set your account to always use https, you might have trouble signing in with a second account after enabling offline and signing out of the first account.
- If you've also checked 'Remember me' when signing in, you'll have trouble signing back in to the first account.

To fix the 'infinite loop' that you'll see on signing in, clear your cache and cookies.
