When you start Outlook Express, the contents of your Inbox folder may be missing. The contents may be replaced with a new first-run "Welcome to Microsoft Outlook Express" message. You do not receive a warning that the email messages have been deleted, and the missing email messages are not in the Deleted Items folder.
This issue may occur if you use the McAfee VirusScan antivirus program email scanning function. If the McAfee VirusScan antivirus program is installed, the email scanning features of the VirusScan program may cause the Inbox database file to be corrupted. When the email scanning function is being used, database corruption may occur.
The Inbox.dbx file is the Outlook Express database file that is used for the Inbox folder. If this corruption occurs, the next time that you start Outlook Express, the Inbox.dbx database file is checked for consistency, the data that the VirusScan program corrupted is deleted, and a new first-run "Welcome to Microsoft Outlook Express" message is generated.
