Lost old emails :(

What happened to my live email account? When i was going to check my live email last month, i was surprised to see a different look, the new outlook that is. That's fine with me, everything changes, it gives a fresher feeling and experience. But what frustrates me is the fact that all my old emails were gone! Just the welcome message from outlook, nothing in the inbox or the sent folder, or even in archived or deleted folder. I've been using my live email account for years without problems. I'm on and off with that account and i didn't lose any saved emails. I feel secured. But now, they're all gone and it's really frustrating. So i waited for a couple of weeks thinking it's part of the upgrade process, maybe it will come back but checking again now, they're still not there. All i have now are the new emails i received.I don't care if the look changes from time to time, all i want is my old saved emails back. I'm sure my account wasn't hacked, about my emails being 365 years old blah blah, i check them periodically, the last time i checked it, when it was still live.com, the oldest email which was the very first welcome message when i signed up was still there, i also tried that recover deleted messages thing in deleted folder with no success, about my browsers, they're all up to date, so i think that's not the problem, i didn't change any of the settings either, i really do think it's a bug of the new outlook email. Man, it's really frustrating! I hope u can do something about this to lighten up my day! I want my old emails BACK! >.<
