Please help me retrieve old emails!

All my emails and folders have been deleted but all my contacts are still there.  I asked for help via Answer Desk and I was told that once an account is inactive, everything would be deleted including contacts and the account would be deactivated.  I am still able to access my account and my contacts are still there so I am not sure what is wrong.

I tried “recover deleted messages” several times but it still doesn’t work.

On several threads I noticed that some forum moderators were able to help others (who were in the same position as me) retrieve old important emails from years ago.  Please, I really need to retrieve some important emails. 

Thank you
