I have an automatic record creation and update rule running in CRM 2016 Update 2.2 on premise. I am not using an Email Router. Everything is set up for Server Side Synchronization. The owner of the record creation rule is a user in the CRM organization who has the system administrator role. The queue owner is the same user in the CRM organization with system administrator role. This user does not have a mailbox. The mailbox for the queue is of a user who is not a user in the CRM organization. Testing and enabling of the mailbox is successful for both inbound and outbound mail. The mailbox for the queue specifies the credentials for the AD account of the mailbox. The output of the system job created when the queue receives an email indicates that the email auto response has failed. There is a message of "The message cannot be sent to all selected recipients. Verify that both the sender and the recipients have valid email addresses, and that the recipients are allowed to receive emails" in a gold bar when viewing the system job. If I view the properties of the task step for sending the auto reply email it shows {null(Channel Properties)} in the From field, {From(Email)} in the To field, the template that I want to reply with and {Case(Create(Case))} in the regarding field. The original sender of the email obviously never receives the response.
Do I have this configured incorrectly or do I need to do some additional configuration in Exchange on the mailbox for the queue?
