Junk hotmail removed when I open mail app on ipad3

When I look at my hotmail on the computer I have mail in junk & folders.

I have tried to synchronise mail received on my Ipad3 using settings. When I open the mail app the junk is there momentarily until the mail updates. Junk mail is then wiped out & of course never to return. The newly lost mail is also gone if I open my hotmail straightway on the computer.
There are some other Hotmail folders with mail stored but these aren't transferred to the Hotmail app. I have lost from other folders.
