CAUSE

Most of the time, these symptoms are caused by a corruption in the Address Book. Frequently, the corruption occurs over time in address books that were created in older versions of Outlook Express. Earlier versions of Outlook Express did not detect this corruption, and the address book functionality was not affected. After you install cumulative security update 911567, Outlook Express examines each address book file for corruption. If Outlook Express detects corruption, you receive an error message.

Copy the .wab file that is located in the following folder:
C:\Documents and Settings\<user>\Application Data\Microsoft\Address Book\<user.wab>
Paste a copy of this file in the following folder:
C:\Documents and Settings\<user>\Desktop\backup.wab
Note In this step, <user> is your Microsoft Windows user name. Make sure there is no <user>.wab file on your Desktop.
Click Start, click Run, type cmd, and then click OK.
At the command prompt, type the following, and then press ENTER:
Del "C:\Documents and Settings\<user>\Application Data\Microsoft\Address Book\<user>.wab"
Start Outlook Express.
On the Tools menu, click Address Book. Notice that the Address Book does not contain any contacts.

Note If you find more than one .wab file, rename the user name with which you are currently logged in. If the user name is the default user name, the file name is Default.wab.

After you apply these changes, import all contacts that are contained in the old .wab file to the new profile that you have created. All contacts that are contained in the .wab file are imported to the new profile. During importing, folders are not recognized. Therefore, all contacts are imported to the profile. If you have shared groups, these groups are imported to the profile.

Note This resolution does not apply to Outlook Express 5.5 Service Pack 2 (SP2) on a computer that is running Microsoft Windows 2000 Service Pack 4 (SP4). Microsoft is researching this problem and will post more information in this article when the information becomes available.
