Thanks Michael! Actually the goal is the CIO sent a message and wants to see who read it. :)
Haven't been able to find if the read information is stored in the Sent Item copy of the message or the recipient's Inbox version. If it's in the Sent Items version it wouldn't be too bad. When the user uses ECP he's just checking the local copy. If not, the ECP will have to check every recipient of the message. This customer might send messages to 10,000 or more recipients.

I doubt it would be noticeable, but I have never seen any performance measurements on it. What is the actual goal? It might be easier to accomplish the desired goal with MAPI or EWS, unless the goal is "I'm the CEO and I want to see who has read the emails I send!" :) I fiddled around with this for a little while (always fun to learn new things) and getting the right message tracking report is a bit finicky. But doing it with AQS is easy "Received:Today AND Subject:'test' NOT Is:Read". But message-tracking is much more scalable than EWS if you are tracking all mailboxes and making regular search requests. One final comment: ReadTrackingEnabled only works for internally delivered email. It works differently than "Read Receipt Requested".

I have a customer that wants to enable ReadTrackingEnabled in their Exchange 2010 environment. Does anyone know how much of a performance hit this would be? Thanks, Joe Barrett
