Expression Web breaks Outlook 2003 Junk E-mail Functionality

Installing the Expression Web Trial on a workstation with Outlook 2003 will result in Outlook’s Junk E-mail feature ceasing to function. I have tested this in POP and IMAP accounts with the same result.

There are two solutions that worked for me to bring Outlook’s junk e-mail processing back:

  1. Running ‘Detect and Repair’ from the Outlook Help menu

  2. Removing the latest Outlook junk email filter using Add/Remove Programs in Control Panel (with Show Updates selected) and reapplying it through Microsoft Update.
