Need to restore messages that were deleted 6 months ago.

I need to recover some important messages from a specific person that I deleted about 6-7 months ago. They are no longer in deleted folder because it was emptied numerous times and these messages are very important to me for a court case. Attorney said that messages are recoverable up to few years but the only way to get them is through Microsoft support.

Tried to contact Live support but was suggest to sign up for Hotmail plus, after I did so, found out there was no member customer service for subscribed members as was explained. After contacting Live support second time, was suggested to post a message here for help. Please help, trial is in few weeks and not much time left.

Thank you to whoever is out there to help in advance.
