SYMPTOMS

When you edit a contact in the Microsoft Outlook Express Windows Address Book (WAB), a file that is named "~" may appear on the desktop or in another location on the hard disk, such as C:\Program Files\Outlook Express.

CAUSE

This problem may occur if the following conditions are true:

You are running Microsoft Internet Explorer 6 Service Pack 1 (SP1).
You have installed the update that is described in either of the following Microsoft Knowledge Base articles:
331923 An overview of the Cumulative Update for Outlook Express 6.0 S331923
330994 MS03-014: April, 2003, Cumulative patch for Outlook Express

The problem is caused by an error that results from the installation of either of these updates. When you edit the WAB, Outlook Express creates a backup file that is named User_Name.wa~. The backup file is stored in the following folder:

C:\Documents and Settings\User_Name\Application Data\Microsoft\Address Book

However, when this problem occurs, Outlook Express creates a backup file that is named "~." The backup file may be stored on the desktop or in another location, including the following folder:

C:\Program Files\Outlook Express

RESOLUTION

Update information

To resolve this problem, install security update 823353. For additional information about security update 823353, visit the following Microsoft Web site:

http://www.microsoft.com/technet/security/bulletin/ms04-018.mspx

WORKAROUND

To work around this problem, move the "~" file to a location that you want.

Note Do not delete the file because it is a backup of the Windows Address Book. You may need the backup file if you lose the Windows Address Book. To use the backup file, you must rename the backup file User_Name.wab and then copy the file to the following folder:

C:\Documents and Settings\User_Name\Application Data\Microsoft\Address Book
