If your Yahoo emails have suddenly disappeared from your inbox, several effective solutions can help recover them. First, check your Trash and Spam folders, as emails sometimes get filtered incorrectly. Next, verify your account settings to ensure POP/IMAP configurations haven’t changed accidentally. Additionally, sign out of all devices and clear your browser cache before signing back in. Another important step involves checking any filters or rules that might automatically move specific emails. If using the Yahoo Mail app, try uninstalling and reinstalling it to resolve sync issues.
