I'm having an issue with meeting forward notifications in Exchange 2010 SP3. I'm working on an integration project with an existing system using the EWS Managed API. Part of this system is handling forward notifications and responses. However, we've hit an issue regarding the way forwards are generated by Exchange.

In short, when a meeting request is forwarded to an external address (could be an Exchange server outside of our domain, gmail, or anything, really), the notification they receive places the meeting owner in the "sent representing" field, not the person who actually sent the forward. As a result, any responses from the forward recipient will go directly back to the organizer, and the user who forwarded the request may not even be visible. We do not want this to happen. We'd prefer that the forward show the person who actually sent it as the sender, and as a result, the response should go directly back to them, not the organizer.

Is this possible, either through settings or flags on the Appointment object itself or through some additional configuration options in Exchange? Installing a third-party transport agent (even one that we write) is probably out of the question.

What if you "Forward as iCalendar"
