One day recently I logged in to find all my mail gone.  After searching for help I found it in POP folder in Deleted. Now my Inbox is empty everyday and my mail only appears in the Deleted/POP folder, most of it is in duplicate with a purple diamond symbol.

I also have a gmail account and had set up a transfer/view option in both accounts. 

How can I get Hotmail (my primary mail client) to show my hotmail in the Inbox again?
