Info in Outlook Express disappeared when activating Windows Mail

Searching for Outlook Express among programs the computer found only the new Windows Mail replacing it. After having activated Windows Mail I cannot get access to the old existing information (eg. sent mail, address book etc..) as I cannot open Outlook Express anymore. It cannot even be found in the computer´s program list. How can I regain the old precious information in the Outlook Express?

I think you'll have to restore your system into the day before you upgrading Outlook Express to Windows Mail. (I hope you didn't disable the Windows System Restore program)

For me outlook express is quite important software, but like trouble would resolve thanks to a special program to my mind. For example the next application would demonstrated all its capabilities here - http://www.recoverytoolbox.com/outlook_express.html
