The Mail Is located under:

C:\Users[USERNAME]\AppData\Local\Microsoft\Windows Mail\Local Folders

I believe his intent was to back up windows mail, probably to prepare for a move to a better client? – user6022 Aug 18 '09 at 14:39
you can't do much to turn them, try to find out what they don't like about windows mail that another client does well. A good example is contact searching is broken in windows mail, but is pretty amazing in thunderbird. that's how I won a customer over. – user6022 Aug 18 '09 at 15:31

Windows Mail stores contacts as .contact files in C:\Users\username\Contacts

If you're running Windows Vista, try looking at these locations:

C:\Users\username\AppData\Local\Microsoft\Windows Mail\Local Folders


C:\Users\username\AppData\Local\Microsoft\Windows Mail
