The normal deletion schedule for Trash is 15 days. But you can right-click on the Trash folder and you will see "Recover Deleted Items" as an option. Click on that and see if you can spot the message you want. Then move it back to the Inbox.
Thank you Latoque,I found what I was looking for,moved them to inbox went there,but nothing in the box. Went back to trash bin and looked again now they are gone. thought I had it there for a moment.Well at least we tried,you were great for helping me.
