I read the FAQ here but it does not work to recover the mail from the folders. 

On 13 August I have contact Microsoft and talked to Nicholas on Aug 13, 2013 11:15:15 AM EST, which he referred to contact my regional Microsoft subsidiary. 

The following day, I called up Microsoft Singapore to seek solution with Magaret Hansen. He provided me with the solution here, but it doesn't work out too. In the end, he requested me to post my question and request over here on 15 August 2013. I need to recover the mail as my insurance claim evidence related mail has been deleted and it need to be recovered to file my insurance claim. 

Thank you for the kind assistance.
