OL98: ErrMsg: "Invalid Page Fault in Module Fldpub.dll"

When you are using the Net Folders feature of Microsoft Outlook 98, and you open Outlook, you may receive the following error message: Or, although Outlook may start without the error, the message may occur when you try to send a Net Folders update or subscription. The memory address referenced may vary.

This error may be caused by either of the following:

• An improper registration of the components that Net Folders uses to share items and send updates.
  
  -or-
• There may be damage to the files that make up the Net Folders feature set.

Follow the steps in each of these methods until your problem is resolved.

Method 1

When the Net Folders option is selected in the Add Components option of Outlook 98 Active Setup, a utility called Nfclean.exe is installed. If you run the Nfclean utility, your Net folders may be removed.
