MORE INFORMATION
WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

HKEY_CURRENT_USER\SOFTWARE\Microsoft\Wab\Wab4

In the right pane, double-click UseOutlook, and then change the Value data from 1 to 0.Click OK, and then close the Registry Editor. You now may be able to open old and new messages and access the address book and not receive error messages.
