recover deleted email for legal issue

Dear Zoho Support Team,

I am the IT admin of our company.  Now we are in a situation that needs your help.

We are in a lawsuit that one of the email is key evidence.  But the email was deleted a few month ago from account admin@wesharee.com (alias domain admin@housesigma.com).

The email should be deleted after 2018-07-20.  Please help me recover the email.  If you need any other info, please let me know.

Thanks!
Reed
