Hello,Did you do it from the web browser or from an email program on your computer like Microsoft Outlook?
May I connect with you and take a look?
Okay, I can explain both possible situations to you through here then
1. If you access your email through an email client like Outlook, Windows Live Mail, Thunderbird, etc and the email was deleted, there's a chance for it to be recovered since the emails get stored on your computer as a file at some point and files are recoverable.2. If it's all been done through your web browser then it's most likely only stored on the mail server which we have no control over and therefore non-recoverable unless you send in a request directly to Yahoo using this link.
If you can have the two emails re-sent that will be your easiest option!
Did you require anymore assistance with this or is that all the info you needed?
