outlook and mail

I have inquiry about hotmail account (outlook now), the old emails I received more than 2 weeks suddenly end up in trash (delete). 

I have also ASUS windows 8 laptop and I am using mail application as the default email client, I added hotmail account, also I noticed that the old emails (<2 weeks) goes to the trash.

when I talked earlier with Microsoft regarding different issues with hotmail, I think if I am not wrong, they said similar thing for old emails. So I thought to endorse this issue to you guys, maybe someone witness similar thing and found a solution for.

thanks
