I believe accidentally deleted important emails on March, april and may 2013. Since I deleted more emails after that when trying the option available on the trash folder it does restore only the recently deleted emails. I've heard MS keep copy of the emails on their backup server for couple of years. Is it possible to get copy of some important emails I deleted back on  March, april and may 2013, and if you charge fees for this restoration, please provide me with copy of the bill.

Thank you
