I'm having an issue, I have an On-Premise CRM Dynamics environment with Server Side synchronization, the sync works fine. When creating appointments the System Users receive a meeting invite, but this is not sent to contacts in the system (even though some of them are emails from the same AD).
Is there an error log I can check, or some extra configuration needed in exchange server for it to work?
P.S. I'm attaching the current configuration.
