Question about Outlook Express

This will sound very silly of me but as i was clearing out my Hotmail i deleted everything. Would it be possible to recover them all even if this is a roll back to yesterday.

I tried the recover deleted emails but this didn't work i will most likely delete most of the emails again but i require some of the important documents i deleted. 

I feel like a silly man didn't know it would delete the files in the document area to now i realize that that just looks for documents in all your emails.

Thanks in advance.
