Yahoo emails can vanish because of accidental deletion, automated filtering (e.g., spam or trash), account hacking, sync errors, or server problems. Look in the Trash, Spam, and All Mail folders first. Check filters or forwarding settings in Yahoo Mail Settings, and make sure no unauthorized access took place.

Nonetheless, there are some restrictions, such as irretrievable emails if deleted or emptied from Trash once and for all after 7 days. Server crashes can hinder retrieval, and third-party app sync failures (e.g., IMAP) can lead to data loss.
