Deleted User Name And Lost All The Emails

Vista Home Premium, began getting message that c:users(user name)AppDataRoaming is corrupt and unreadable. Used Dell online technical support. They copied all the files under the username to a backup location, created a new username, and then copied the files back in. Basically copied the directory C:users(user name) to C:users(user name2). Then deleted the user name that wasn't working in the control panel. Looks great except all my wife's emails are now gone - and she had multiple folders with emails stored in them and thousands of deleted emails she referred to. Mad as a hornet!

Is there any way of recovering the deleted email files and then getting them back into Mail? I am trying Pareto Logic Data Recovery Program to search for the directory that was deleted that stores the emails C:users(user name)AppDataLocalMicrosoftWindows MailLocal Folders. So far it is only finding folders with (user name2).I realize now I should have exported all the mail to a backup file before deleting the username, but the tech guy didn't tell me to do that before we deleted the old user name.
