I accidentally deleted my old and new emails. New ones are coming in and they
Are still there but I need the deleted ones.

First its not a good idea to piggyback your question on someone else's. This can lead to confusion. You should start a new thread. So I've moved your question to its own thread.

I assume you are asking about Yahoo e-mails since that was the subject of the other thread. If so, unless the e-mails are in your Deleted or Trash folders, they are gone.
