I found the following on Outlook 2003 Help and How-to

"Rules and the Junk E-mail Filter
Rules are now designed so that they do not act on messages that are moved to the Junk E-mail folder.
This keeps e-mail you mark as junk in the correct place rather than moving it to another folder
according to a rule that would otherwise apply"

This feature is introduced with Microsoft Office 2003 Service Pack 1.

However it don't work with Outlook 2003 SP3

Any ideas who to troubleshoot?

Thanks in advance
