Tips for troubleshooting Out of Office replies

We are running an Exchange 2007 environment, and the users are all a mix of Office 2003 and Office 2007.  
I have one user in particular, running Office 2007, who has been having trouble with Out of Office messages.  The messages work fine when sent from people INSIDE our organization, but anyone from OUTSIDE the organization does not receive any out of office reply.  I have verified that the out of office message is turned on for external emails, and that it is set to send to every external address, not just those in the contacts list.  
I have already created a new profile on a new computer to rule that out.  I also used the suggestions here
to try to track down the issue.  When using the MDBVU32 tool, I came across other files that started with "cb:", but didnt delete them as they referenced OWA and BlackBerry folder settings.  I wasn't sure if they would regenerate themselves, I didnt want to break his mailbox more than it is.  

I am open to any and all suggestions, even deleting those "cb:" files if you think it will help.  

Let me know if there is other info that will be useful.

Using the management console for exchange click on Hub transport and then remote domain. The settings here are probably blocking your out of office replies from going to external recipients.

Thank you so much for that!  It turns out the setting for External OOF was set to not allow anything.  I didn't even know that setting existed.  Thanks again!
