Not receiving any emails in my outlook account

I have no new emails in my hotmail inbox today which is highly unusual but not impossible, so I sent myself emails from my outlook account and from a separate account and I received neither one of them. If anyone has found a solution to this problem which will actually work I would appreciate any help you could provide, I am becoming increasingly frustrated with the myriad of problems with MSN, outlook and internet explorer, I am considering closing my account when my current membership expires.
