Hi again,
We have investigated the issue here and unfortunately the email has been deleted. This can't now be recovered. We archived your mail on the 12th December as you hadn't logged in to it since the 31st August, and emailed you informing you of this on the same day. Once we archive email there is a period of 30 days were we keep this on our servers, after this date the archive is removed and the mail not retrievable. You posted in here on the 11th Jan asking what had happened, this wasn't picked up until the 14th Jan and no other method had been used to ask us to restore this.
We ran the unarchive process on the 14th Jan(and twice since), and because the script ran without errors it was believed this had worked correctly.
We realised today that the 14th Jan was more than 30 days from the archive and therefore it would not be able to restore this.
Sorry if it's not the answer you wanted, however this is what has occurred.
