The webmail service can only recover emails that have been permanently deleted within seven days. However, if you use Outlook or any other mail program and added your Yahoo account, you may retrieve messages that were erased years ago.
The simplest way to recover deleted Yahoo emails is to access the Trash folder and undelete them immediately. If you cannot find your email in the Trash folder, please contact Yahoo to have your account restored so you may retrieve those communications.
It’s quite easy to recover emails that have been permanently erased from your Trash folder by someone else. Even if Yahoo has emptied the Trash folder and destroyed a message, it may still be retrieved. When requested, Yahoo attempts to restore your entire email account back to within the last seven days, potentially bringing back emails that are otherwise lost.
It’s quite unlikely you’ll be able to retrieve something deleted more than 30 days ago; there is no such feature available in Gmail. You can contact the individual you sent the email to and ask whether they still have it. If it’s an email from someone else, you may inquire as to whether they saved a copy.
If you haven’t logged into your Yahoo Mail account for more than a year, Yahoo may remove your messages from its servers in order to make room for new users. Inactive accounts contribute to the overall sluggishness of the service, so keeping things tidy on Yahoo!’s end helps the mail service be quick and dependable for those who use it.
