Up until 3 days ago my microsoft account was working just like always.  Suddenly I stopped receiving anything from anyone who has my hotmail account as my primary address.  I cleared the cache, checked my browser.  It's all current.  I usually have at least 20 emails a day in this account, now nothing.  I'm not getting any of my paypal e mails either and I'm a seller on eBay.  This is not good.  Help!
