I was sent an email on 9/4/2008 and I can't seem to locate it wondering how I can find it
It was from vonage and I need the email as proof that they received my device that I returned I had it on the screen when I searched I tried to forward it to them but it would not let me and now the email is gone even when I search it

If you replied to the message, it might show up in the sent items folder. Most email empty the trash folder after 30 days. Given the date, it might be too late. Do you backup your email folder with your system backups? If so, it might be in there.
