It appears this file is a database about the
mail, which is stored as EML files in the appropriate subfolders under
C:\Users\UserName\AppData\Local\Microsoft\Windows Mail\Local Folders and does not contain your emails.
Sorry to hear about your loss.
As I was formating my laptop, I copied WindowsMial.MSMessageStore file to pendrive instead of using File_Export_Messages. How can I view these messages now? I have windows mail on windows vista home basic. I have another PC with XP & outlook express. I can use any of these. I copied & replaced the WindowsMial.MSMessageStore file at its usual location but it did not work.
Any help shall be highly appreciated.
