Outlook question: Rules Wizard: "Rule in error"

Factual Questions
1

I get about 50 spams a day, and I have my Rules Wizard set to delete things with any of two dozen tell-tale things in the letter. Things like having viagra in the message, or “moviebux.com” somewhere in the header, a cc: to a known spam address, etc.

But I keep getting my rules turned off by the wizard with the message: Rules in Error: You don’t have appropriate permission to perform this operation.

Clearly a bug. The “operation” is to delete the message. And of course I have “permission”.
What it seems to mean is that the message was already deleted by a prior rule, so when accessing it they get an access error and guess wrongly what caused it.
Instead of realizing the problem was previously solved, they panic and remove one rule and nag me about it. The nagging is as much work as just looking for spam myself without the wizard.

OK, but when I leave the rule turned off those messages will get through.
If I try to rearrange the messages, a different rule will be in error.

Anybody know about Rules Wizard? Any suggestions?

I think I found what causes this, and a solution.

The spammer has my email address in the distribution list twice, once with my user name attached and once as just the plain address. Guess they combined lists culled from different places. So Outlook tries to delete it twice.

The cure is to select “action to be taken” as “Permanently Delete” and also select “Stop Processing All Rules”

Why Permanently Delete doesn’t automatically imply “and Stop Processing” is a Microsoft Mystery.
