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 described are:

Method 1: 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, 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. On the Windows Taskbar, click Start, point to Find and 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 click Find Now.


  6. In the Name list, right-click the file Extend.dat, and on the shortcut menu, click Rename, then change the file extension from "dat" to "old," and press ENTER.


  7. On the File menu, click Close to exit Find File.


  8. Restart Outlook. Restarting Outlook creates a new Extend.dat file.


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 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 3: Create a New Profile and Personal Folders File

NOTE: If you are using the Internet Mail Only (IMO) version of Outlook, skip to the section titled "Create a New Internet Mail Only (IMO) Profile."

If you are using the Corporate Workgroup version (CW) of Outlook, create a new Profile and then create a new set of Personal Folders.

Create a New Profile (CW)

To create a new profile, follow these steps:

  1. In Windows Control Panel, double-click the Mail And Fax icon. (The icon is a Mail icon if you did not install fax services.)

  3. Click Add to start the Inbox Setup Wizard.


  4. Check that the default is set to "Use the following information services."


  5. Click to clear all services except the one you are troubleshooting. For troubleshooting purposes, add only one service at a time.


  6. Click Next and in the Profile Name box, type a name for the new profile.


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

    NOTE: Since you are not using the old .pst file while troubleshooting, you will not see any of your old .pst folders or files.


Create a New Internet Mail Only (IMO) Profile

If you have installed the Internet Mail Only version of Outlook, follow these steps:

  1. Click Start, point to Settings, then click Control Panel.


  2. Double-click the Mail icon.


  3. Select and remove each Internet mail account from the Internet Accounts Manager. Be sure you know all the Properties for each account before removing.

    NOTE: Do not remove Fax accounts.


  4. Add the Accounts back one at a time.
