Rules in error

[Alan]

I have been using Outlook for sometime, but recently have
set up several rules to help filter e-mail. I have the
following rules running in this order
1. Exception list
2. Redirects e-mail to a folder based on account rec. on
3. same as rule two but a different account.
4. Permanently delete any message sent from an account on
the adult list.
5. Pemranently delete any message containing specfic words
in there subject.
What is happening is when rule five is activated, at times
I get a "Rules In Error" message box. The box states that
rule 5 is in error, that I do not have permissions to do
that. I have swapped the position of rule 4 and rule 5,
the error then states that the new rule 5 is in error.
Both rules can be run manualy even togther from the run
now menu with no problems.
Any ideas.
Thanks
Alan
