An important email has been filtered in Junk (outlook). I saw the email only 2 days ago, when the sender informed me that they had sent me a message on an important issue. Now this person is suing me for not acting on that particular issue. The only way I can cancel the appeal is if I can prove that this email went to my junk folder and prove that I opened the message only recently. Can anyone suggest how I might go about this? I would appreciate your help.
Thank you
