Hotmail not working on ipad2

Cwsse

New Email
My hotmail is not working on my ipad2. I can use my hotmail account from the mail icon on ipad2 but when I sign into hotmail through safari or another Internet connection, I can not send, delete or go to additional pages of my hotmail account. It seemed to be working until I upgraded to the iOS 5.1.
Any suggestion/help would be appreciated.
Thanks.
