Imported sent messages – All messages display the owners account address as the destination address?

I imported Windows live mail messages from XP to 8.1... everything is ok except for the fact that the "Sent" messages are listed as sent to "owners_address" which is really the "source" address for all these old sent messages....Client needs these back to how they were on the XP machine... This is a result of importing using the import tool method from the file menu, and the same result after I did it manually by dragging old files into the new "Windows live mail" sub-directory (sent folder).... I think its a setting or something I need to change.
