Email problem with Iphone,

I have been reading that the problem with Mobil devices still on. I can not see as well any email (old ones) on my I phone, I do receive the new ones but after the next day those are not in the inbox anymore or if i delete them, they are gonne as well. If i refresh it, it gets connected and updated but nothing else.
On a pc the email is working fine.

Can you please look up at my email>

Thanks!

Paulina
