Because Yahoo Mail gives you unlimited storage space and doesn’t delete old messages unless you do, you can always find old emails by searching your inbox or sent folder. If you accidentally deleted emails or feel you’ve lost some for an unknown reason, Yahoo has a restore process for you to get them back by restoring your mailbox to an earlier time. There are caveats, however. You’ll lose any existing email because you’re essentially going back in time. You can only retrieve a message that’s been lost within the last 48 hours. You can’t specify a time frame, such as a particular week, for instance. Writer Bio
