Outlook 2000 auto-forward rule doesn't work?

We have an all Win2K server/professional network with Exchange 2K and Outlook2K environment. I've got a user needing to setup what seems like a simple rule in Outlook2000 to autoforward all incoming messages in their inbox to an external comcast.net email address.

I've tested and been able to send a simple test email to the comcast.net email account, then verified it via comcast's web interface to ensure it worked.

The rule I'm trying to enable is simple. Forward ALL incoming email to this one external email account??

Can anyone clarify what it takes to activate a server-side rule using the Rules Wizard?

Is there any log or error file facility I could look at to trace the problem?

Thanks,

Note that if a mailbox is over its size limit, it cannot execute any rules that will send replies or forward items.
