My DBX files are not small but Outlook Express cannot display messages from them. What DBX repair tool can solve this problem?
See this thread: http://answers.microsoft.com/en-us/windows/forum/windows_xp-windows_programs/outlook-express-repairrecovery-of-corrupted-dbx/8bbcc787-4d6c-4bed-89f4-96c4d0a4e7be
Also, try importing the messages to other email programs that can read DBX (e.g. MS Outlook, Windows Live Mail, Thunderbird).
