Hello Vasil
I have configured the user report submission to submit the emails to a custom organisation mailbox when the users use the outlook phishing report addin but it does not seem to work yet as I don't see the reported messages in the inbox if the custom mailbox. so I was thinking maybe there is some tweaking I need to do with the powershell. also I can't seem to find documentations on expected behaviors and how to troubleshoot this feature.
