I have a client that is still on Microsoft Dynamics 365Version 1612 (8.2.10.24) (DB 8.2.10.24) on-premises.
Inbound emails to a service email address are created as queue items, and an automated workflow response is sent to the sender of the originating email (simple enough)
However the moment the subject line of the email begins with Fwd: the automated response is not sent, the workflow is not even triggered, absolutely nothing happens.
Checking the history I see that it has been like this since 2018 which is possibly when this client first started using CRM. (I just started with this client, there were other consultants before me)
If I go to these emails and click Reply, Reply All or Forward I get an error
And log details:
