I've been having an Yahoo email account (personal) for more than a decade. It was a main account in the beginning, and I later started using another email from a different vendor as a main account. I used to login occasionally to my Yahoo account and then the frequency got lesser. **I believe I last used my account towards the end of ****. Post that when I logged in today (**th May ****), I was able to login successfully with my old password, but was utterly shocked and dismayed to find out all of emails in all folders (like inbox, sent, trash, etc) have VANISHED into thin air, so did my customized folders. **It was as though someone accessed my account and wiped it clean, or not sure if it is a case of a deleted or "refreshed" account for not using the email account for more than ** or ** months. Either ways it is like a brand new account. **I've lost several important and personal emails of great value and importance. **KIND HELP NEEDED:*Is there any remotest chance I can get back all of my old emails of more than ** years?**Any help will be deeply and gratefully appreciated. Many thanks in advance with the deepest gratitude.
