Recover deleted Google Apps email messages
When a user clicks Delete, the Google Apps email message moves to the Trash, but it remains available to the user for 30 days. If it has been fewer than 30 days and the message hasn't been permanently deleted, the user can follow these steps to put the email message back in the inbox:
- Sign in to Gmail.
- Click Trash along the left side of any Gmail page.
- Locate the message you'd like to move to your inbox, and check the box next to the sender's name.
- Click Move to Inbox.
Can’t find a message
Sometimes missing messages are not shown in search results, but they were not deleted. The user may need to search with different terms to find the message. Start with fewer search terms, and look beyond the first page of results.
Also, note that Gmail search doesn't allow partial matches and won't return a result if a word is misspelled or if the search terms are too specific (i.e. a word in the 'Subject:' search field matches but the address you've put in the 'From:' field does not). We strongly recommend searching with only the information you're sure will match the message.
Recovering Deleted Messages with the Email Audit API
If you can't find your messages in All Mail, Spam, or Trash, or by performing a search, then they've been permanently removed from Gmail, possibly deleted by someone else. We regret that we are unable to recover messages that have been permanently deleted. If you're concerned that someone may have gained access to your address, we suggest that you take the following measures to protect your account.
Also, please check with your domain administrator to see if two-step verification is available for your domain. Please consult our overview on two-step verification for Google Apps accounts.
