CAUSE

RESOLUTION

To resolve this problem, follow these steps:

Start Outlook.
On the Tools menu, click Options to open the Options dialog box.
In the Options dialog box, click the Other tab.
Click Advanced Options.
Click Add-in Manager to open the Add-in dialog box.
In the Add-in list, click to clear the Netscape Navigator check box. This check box may also be displayed as the Netscape Extensions check box.
Click OK three times to close all of the open dialog boxes.

The Nxpext32.dll file is a Netscape Navigator version 2.0 or 3.0 file. Add/Remove Programs in Control Panel removes all of the references to this file in the Windows Registry; however references remain in the Add-in Manager in Outlook.
