That email address was working as of mid-April because folks in [link disabled after threads merged] reported success with it.
This issue just continues to be a ridiculous PIA with no rhyme or reason and no consistency among Marriott Rewards or Owner Services personnel. Sometimes X email address works, sometimes it doesn't. Sometimes Y email address works, sometimes not. Sometime X phone number works, sometimes Y phone number, sometimes "Click to Chat", sometimes not ... and on and on and on. In my case I've never met with success, am right now sitting on an upcoming Phuket Beach Club exchange and have given up.
There is a disconnect in the system whereby if the MR Number of the person who makes the original reservation is attached to it, then it is not automatically deleted or changed when the name on the reservation is changed. So the first MR Number attached to an II confirmation doesn't fall off if, for examples, an owner reserves a Week through Owner Services and deposits it, or if an II exchanger attaches a Guest Certificate to it, or if an exchanger releases a confirmed exchange back to the II pool, or anything else that results in a name change. That's why the official policy is that MR Numbers are not supposed to be attached to any II inventory until the resorts are notified of the actual guest's name, at the earliest by way of the pre-arrival email or at check-in.
Its only effect isn't us not being able to see our own pending II exchanges in the Upcoming Reservations portal in our Marriott Rewards accounts. It sometimes results in the contact and MI account information of anybody whose name is attached during the processes being released to the originator of the reservation. It also can result in the originator seeing a reservation in his/her Upcoming Reservations that s/he's actually given up, and/or an originator getting Elite Night and incidental spend credits for stays which they never make. And, Platinum Marriott Rewards Members may not be offered the guaranteed Arrival Gift or be able to invoke the $100 Guarantee when it's not offered, because how can the check-in personnel know it's supposed to be offered if the MR Number can't be attached? All of these items should be reason enough for MVW and MI to prioritize this as a legitimate problem.
I wish they would fix the disconnect so that either MR Numbers could be changed with each transaction, or, so that every Marriott/II rep would be on the same page and not attach any numbers. Obviously, the first is ideal but IMO if they can't do that then consistency is more important than frustrating us to no end.

Coincidentally, this is something that I've brought to the attention of MVW in the past, and I included another blurb about it in the recent email I've sent about the Banking rules related to the 4/30/15 DC Status Tier changes.
