Set auto reply to all incoming messages for particular mailbox Exchange 2010
I am looking for a way to set an automated response on a mailbox in Exchange 2010 that will respond to every email sent to the particular mailbox. Automatic Replies/Out of Office will only respond to the sender once. I have also attempted using a Hub transport rule, but the only automated response available is a rejection NDR. With this the response email looks like a rejection and the original message does not make it to the recipients inbox inside of my organization. I've also attempted setting up a rule that responds with an Outlook template, but this does not seem to be working either.
Does anyone know of a 3rd party app that can achieve this for me, or something integrated into Exchange 2010?
