My gut says the contact information is somewhere on hard drive, perhaps under different name and/or extension than ".WAB.
STEPS TAKEN - 1. I have searched for all .WAB files. No contact information was found.
2. In the Address Book, I went to "File", "Import", clicked on "MS Internet mail address book". A window opened asking I choose the ".ABC" file I wish to import. No ".ABC" files were found.
3. I searched for 'MS Internet mail address book". I found many files, some of which had address book in them. None had contact information. Interestingly, there were 2 Address book file with a ".MDB" extension. I tried to open them with Access. Message was these files are not WIN32 files. Also a couple of other files asked whether I wish to "Vcard" as my address book default file ?? (don't understand). I hit "No". The empty address book opened.
Any suggestions?
