When the etp message arrives, I assume you are not clicking on it or opening it, right?

I've had some weird activation issues where the message came into the Inbox and wouldn't process, so I had the user completely shut down their Outlook client and for some odd reason it worked fine after that.... we're using Outlook 2007, though, so may not work the same for you (although I'm not sure why it worked at all!).
