HELP!!

Hotmail is no longer working on my iPhone 4. It started a few days ago. I kept getting the message that my account name or password were incorrect. I tried several times to access it by changing my password and then it locked me out. I had to change it online to get access again.

I tried rebooting my phone..that didnt work. I finally deleted the account from my phone and added it back but now it doesnt receive any emails and the sent, deleted boxes are gone and its not showing the history in my account.

What's going on?

Thanks!
