Messages not showing?

Can anybody tell me please, why my new messages aren’t showing in my inbox ?
The inbox tab on the left say 2, and I’ve had 2 emails telling me they are there, but I can’t see them…
My inbox is not full either

Any ideas please.

its possible the person who sent them has deleted them before you tried to read them… in that situation you would get the notification but they wont move to your inbox

Thanks Rikki…
I have got the (2) on the left side by the inbox tab when I go to my messages, but thats all…
