Outlook 2007 rules

[Col]

Hi all,

We have Outlook 2007 on 2 machines. (Vista SP1, Office 2007 SP1)

On one machine all rules work but on the other machine only the first rule
is ever executed.
All security settings are the same on both machines.
On the machine that runs all the rules, there is vba code to run when new
mail arrives (Application_NewMailEx) but this never executes either.

Both machines were OK with Outlook 2003

Regards
Col
