MORE INFORMATION
This article discusses how to troubleshoot Invalid Page Faults (IPF) in Outllib.dll. The methods described below start with the easiest and most likely fixes, and progress to the more difficult fixes.

The troubleshooting methods listed and described below are:
 * 1) Ensure Microsoft Outlook Express is installed and functioning correctly
 * 2) Rename the Outcmd.dat File
 * 3) Disable Extensions
 * 4) Start in Safe Mode
 * 5) Run the Inbox Repair Tool on your Personal Folder.
 * 6) Create a New Profile and Personal Folders File
 * 7) Reinstall Outlook
 * 8) Check your version of WinFax Pro
 * 9) Do not use Microsoft Word 97 as your e-mail editor

Method 1: Ensure Microsoft Outlook Express Is Installed and Functioning Correctly
If Outlook Express is not installed or functioning correctly, components of Outlook may not function correctly. Ensure that Outlook Express is installed and working without error. For additional information, click the article numbers below to view the articles in the Microsoft Knowledge Base:

Method 2: Rename the Outcmd.dat File
If the IPF occurs when you start Outlook, locate the file Outcmd.dat, rename it to Outcmd.old, and then restart Outlook.
 * 1) Quit Outlook.
 * 2) Click Start, point to Find, and then click Files or Folders.
 * 3) In the Named box, type outcmd.dat.
 * 4) Click to select Include Subfolders, click My Computer, and then click Find Now.
 * 5) Click the file name in the results pane, click Rename on the File menu, type old in place of dat in the file name, and press ENTER.
 * 6) Click Close on the File menu to close the Find window.
 * 7) Start Outlook.

Outcmd.dat stores any custom changes you make to your toolbar options. If renaming this file solves the problem, you must recreate any toolbar customizations.

Method 3: Disable Extensions
Outlook may have problems with incompatible or invalid extension information. Extensions may cause Outlook to not start or create IPFs while running. To troubleshoot extension problems, follow these steps.

If Outlook Does Not Start
If Outlook does not start, try replacing the Extend.dat file. This file caches extension information gathered from the Windows registry. To replace the Extend.dat file, follow these steps:
 * 1) Quit all programs.
 * 2) Click Start, point to Find, and then click Files Or Folders.
 * 3) In the Named box, type extend.dat.
 * 4) In the Look In list, click to select your hard drive.
 * 5) Click to select Include Subfolders, and then click Find Now.
 * 6) In the Name list, right-click the file Extend.dat, and on the shortcut menu, click Rename; change the file extension from dat to old, and then press ENTER.
 * 7) On the File menu, click Close to quit Find File.
 * 8) Restart Outlook. Restarting Outlook creates a new Extend.dat file.

If Outlook Does Start
If you can start Outlook and you suspect an extension problem, follow these steps to disable extensions: >
 * 1) Start Outlook.
 * 2) On the Tools menu, click Options, and then click the Other tab.
 * 3) Click Advanced Options, and then click Add-In Manager.
 * 4) In the Add-in list, click to clear the check box for the add-in you suspect.
 * 5) Click OK three times to close all dialog boxes.

Method 4: Start in Safe Mode

 * 7) Follow the Inbox Setup Wizard prompts, answering the questions for your service. Ensure you specify a new Personal Folders file (*.pst) and do not use the existing file when prompted by the wizard.
