I've reviewed most of the suggestions and helps for recovering a hacked/stolen account but the solutions haven't helped for my case.  Just after my account was overtaken, the hacker got into my account settings and changed my alias (my email account address).  When I follow the steps to reset my password using the stolen email account address, I always get a message that says "That Microsoft account is incorrect, please try again". 

A notification was sent to me at my alternate email address advising me that I had changed my primary alias.  I re-attempted the pw reset with the new alias and I got into my account.  I then changed my password and primary alias once again, exited and logged back into my account, using the new alias and password.  However, my account looks like a brand new one.  All of my contacts, emails, folders, etc are gone.  Can these be recovered?  Thanks.
