Windows Address Book Is Sharing the Contacts Folder from a .pst File
If this is the cause, opening Outlook (IMO) 98, or 2000 on the same computer will cause an error with a message that states that the location, to which mail was being delivered, has changed. If you create a new .pst file, or locate the old .pst file so that Outlook 98 or 2000 is working properly, the Windows Address Book (WAB) link through MAPI to the Contacts folder is re-established, and the WAB will work in Outlook Express or in standalone mode again.

Create a New Windows Address Book (WAB) File
The WAB file may have become damaged or corrupted causing one or both of the above error messages. You will need to rename the existing .wab file and restart Outlook Express(OE). Once started, OE will create a new .WAB file. Microsoft does not recommend that you import the data from the old, damaged .wab file. If you do, you may import the damage into the new .wab file.
 * 1) Click Start, point to Find (Search on Windows 2000 or newer operating systems), and click For Files or Folders.
 * 2) In Search for files or folders named, type. *.wab and click Search Now.
 * 3) In the Search results window, Right-click the file(s) with an extension of ".wab" and then click Rename.
 * 4) Rename the file extension (the three left-most characters in the name) to "old" and press ENTER.

Outlook Express will create a new WAB file the next time you start it. For additional information about how to create a new PST file in Outlook (IMO), click the article numbers below to view the articles in the Microsoft Knowledge Base:
