MPREXE Causes Invalid Page Fault When Checking for Mail

ID: Q171024

The information in this article applies to:
  • Microsoft Outlook 97

SYMPTOMS

When you try to check for new mail in Microsoft Outlook, you may receive the following error message:

MPREXE caused an invalid page fault in module Kernel32.dll


CAUSE

The Windows password list file is damaged.


MORE INFORMATION

Outlook stores mail server passwords in the Windows password list file. When Outlook checks for new mail, it must reference this password list file. The name of the password list file is generated from the name used as the Windows Logon ID, for example <Username>.pwl.

To rebuild the password list file, follow these steps:

  1. On the Windows taskbar, click Start, point to Find, and then click Files Or Folders.


  2. In the Named box, type *.pwl and click Find Now.


  3. Right-click the file titled <username>.pwl, and click Rename on the shortcut menu.


  4. Rename the file to <username>.old, and then press ENTER.

    NOTE: If you are using a personal certificate, you should export it before renaming your .pwl file. If you do not do so, it may be unavailable when you send e-mail. For more information, see the following article in the Microsoft Knowledge Base:

  5. Restart Windows.


When prompted for a name and password, you must type a name. This name will be your Logon ID and will also be used as a name for your new password list file. Entering a password is optional. Leaving the password blank will create what is called a null password. If you use the null password, Windows will not prompt you for a password again.

The first time you run a program that stores a password in the password list file, you will be prompted for a password. If you tell the program to remember the password, it will be stored in the newly created password list file.
