I have a simple rule called "incoming", defined as

apply this rule after message arrives,
run incoming.ThisOutlookSession.CustomMailMessageRule

the rule itself simply writes some headers into a folder

sometimes something in the incoming message causes an error in the rule and
OL2003 pops up a messagebox that the Incoming rule has an error and I have
to manually access Rules and checkbox again the Rule

how can I stop this? why wouldn't the On Error not take care of that?


Sub CustomMailMessageRule(Item as MailItem)

On Error GoTo Quit


Quit:
End Sub
