I know these can be called by different names, but I am not sure if Windows Mail and Windows Live Mail is the same.
If it is, have a read of the information in the post below. You may find it very useful;
I hope that helps.
A friend's Vista laptop was dropped and damaged pretty badly. Rather than pay for repairs, she went out and bought a new laptop. Fortunately the hard drive is still readable. She had been using Windows Mail on the old computer and wants to do the same on the new computer. Can I just copy the contents of \AppData\Local\Microsoft\Windows Mail\Local Folders to the same location on the new Vista computer and be all set?
