How to recover deleted folder from Yahoo.com mail account

Visit Mail.yahoo.com and log in to your Yahoo! Mail account. Click on the folder marked "Trash" on the left-control panel. View the folder's contents to see if your message is inside. If it is, place a check next to the message and click "Move To>Inbox." This restores the deleted message. If it's not, continue to Step 2.
Visit the Yahoo! Deleted mail retrieval page (see Resources). Click on the appropriate link to retrieve your mail, depending on which version of Yahoo! Mail you use. For New Yahoo! Mail, select "New Yahoo! Mail." If you are using Yahoo! Mail Classic, click "Yahoo! Mail Classic."
Type your name into the entry box, and then type your Yahoo! Mail user name. Select the date and time that you would like to roll your inbox back to. For best results, select a date and time 24 hours prior to the current time; this will improve the chances of Yahoo! being able to recover your deleted mail.
Type in a short message to give to the Yahoo! Mail account specialist, if desired. This is optional. If you'd like to describe your situation, feel free to do so, although it will not improve the chances of the specialist recovering your deleted mail. Click "Submit." Yahoo! will get back with you as soon as possible. You'll receive an email regarding the results of the email recovery.

You may check the Trash folder in your Yahoo account. It is usually located in the left side of the page below the Inbox and Spam folders.

It's possible, if it's been less than 24 hours since you deleted those emails to recover by filling out this form.

If more than 24 hours, and the Trash folder has been emptied, there would be no possible way to retrieve deleted emails.

I don't know if you emptied the Trash folder or if Yahoo! did, but it's not a bad idea to get into the habit of NEVER emptying the Trash folder. Yahoo! empties it for us, so there's really no need for that step.

Once you have deleted emails from the Yahoo Spam or Trash folders, they're gone for good.

1. Log into your Yahoo Mail account - http://mail.yahoo.com
   When you delete messages in Yahoo! Mail, they go to your Trash folder. If you delete a message by mistake, for a little while you'll be able to find it in Trash and move it back to your Inbox or another folder. Just remember that messages in your Trash folder can be deleted at any time, without warning.
2. To permanently remove the contents of Trash yourself, just click Empty next to Trash on the left side of the page. When messages are emptied from the trash folder, they are permanently deleted from the Yahoo! Mail server and cannot be recovered.

Try to make a habit of NEVER emptying your Trash folder. The emails in that folder are deleted periodically by Yahoo!, so there's no reason for you to take that step.
