Out of office replies are not sent to external email addresses

When I activate out of office for one of my users, out of office replies are sent to internal users but not external users.  I emailed from my hotmail account a user that had out of office enabled.  Message was recieved OK and an out of office reply sent.  However reply is never received at my hotmail account, in message tracking it says "SMTP Message submitted to categorizer" and does not go past this.
Any help would be appreciated.  Thanks.

Out of office replies are not sent externally by default you need to enable it on the Exchange server
