i using exchange 2016 hybrid environment. i have a shared mailbox and an external contact. i have created an outlook rule to forward the emails from the shared mailbox to the external contact. The external domain is already in accepted domain and i have configured a send connector for it in exchange onprem. in exchange online also i have added the connector to it. I dont see emails are getting forwarded to the external domain. in other words emails should get forwarded to an external contact and this emails go into an application. Experts how do i do message trace and check whether the emails are getting forwarded to external contact so it can be issue at the application side as well. i want to confirm from exchange side if emails are getting forwarded.
