I mistakenly deleted my Hotmail email messages from both my inbox and sent folders for the dates 17/12/2012 and 16/12/2012. In addition, I deleted those very same messages from the deleted folder as well. The problem is that I am even unable to retrieve the aforementioned messages by accessing the "recover delete messages" link access at the bottom of the delete folder. I have tried again and again but to no avail. I really need those messages. Could you please help me in that is there any possibility whatsoever by installing a software or otherwise to retrieve the messages for the aforementioned dates.
