At first glance, I thought I'd hate Windows Mail. But at closer inspection, I found it to be Outlook Express on Steroids. With enough tweaking and tuning I could make it look and act pretty much like O.E.6.
If you already have Windows Mail set up on Vista, getting it over to Win-7 is a piece of cake.
The first trick is to get and install "Take Ownership". InstallTakeOwnership.reg - File Shared from Box.net - Free Online File Storage
Then open the Windows Mail folder in Win-7 and select all the files, then "Take Ownership" of all the files. Then delete them ALL.
Then copy the same files from Vista and paste them into the now-empty Windows Mail folder in Win-7.
Make a shortcut to the Windows Mail executable and put it on the desktop.
Run it and set it up as you would in Vista. Job done.
I've done it several times now and each time I do it.........it just gets easier and easier. But it never fails to work.
Good Luck, y'all !
