Outlook Express users who also use McAfee's antivirus software have reported suffering from mysterious cases of disappearing email. |
An intermittent problem involving the interaction of Windows 2000 or XP with McAfee VirusScan 4.5.1 and Outlook Express 6 means that the index file to existing email folders can become damaged when a user downloads new mail. In extreme cases folders are trashed - all users get is a message saying Welcome to Outlook Express 6 as if they were a new user.
A similar problem involving Outlook Express 5.5 means that all saved mail in a user's Inbox goes away when users download new email. The messages are still present in the .dbx file used by Outlook Express but as the index is damaged, users can't read them from the email client itself.
Jack Clark, product marketing manager from the McAfee division of Network Associates, said the company is aware of the issue but describes this as an "isolated problem", reported by just 12 of its 70 million users.
McAfee has released a hot fix, available from its technical support, which addresses most of the reported problems, but doesn't fix the apparent loss of a user's In-box, according to Clark.
