I have a couple of CRM systems that monitor one mailbox each. We previously used GroupWise, and had a rule that any message that came from Account1 to Account2 would do the following:
Forward to Account1
Modify (prepend can work) the subject line with "(Your inquiry has been received)"
Add special line (disclaimer) at top stating "You should receive a response..."
Rest of message below
Allow original message of Account1 to Account2 go through unmodified
I can do this with an Exchange Rule using redirect, however, the original message doesn't end up in Account2. How can I do this with a rule?
Thank you in advance!
Forward/redirect will not work in this scenario, you are effectively generating a reply. You will not be able to achieve this with transport rules, instead you need client-side code such as the macro used here: https://social.msdn.microsoft.com/Forums/en-US/cdd7cecb-4437-4dc3-b092-4351be6d1955/include-original...
Try to use this flow.
