I have taken a look, and, for me, it was heavy going. Problem being the email itself is still in my inbox, it is an attached image that has gone. I have downloaded Recuva, it has found several thousand images, but so far not the one I wanted.
As everybody has said basically. I have Virgin media broadband that does store ALL emails by default, but I recently changed the settings so it doesn't keep a copy on the server.
Thunderbird 3 does just as I24 says, gives the option to save, the named file still shows although it has been deleted, a windows search doesn't find it, neither does Recuva or PC Inspector File Recovery.
So I am dooooomed.
I shall have to do without it wont I ? Another lesson learned.........the hard way
They were the residue I didn't clear, when I altered the settings the first time. They have several options, and being the cautious person I am didn't want to change too much at the first attempt,so basically everything has been deleted from the time I altered the settings, but what remained behind just stagnated there, until I tweaked another setting that deluged me with some ancient emails.
