Prevent Server-Side Sync from sending appointment email notifications to external recipients 

When an appointment is created in CRM and an internal user an external contact is added in the required field, we see the external contact receiving an email notification instead of the appointment.

Steps to reproduce the issue.

Creating an appointment in CRM and click on save

1. Create two users in CRM


2. One is internal CRM user


3. Second is external contact


4. Then login to CRM


5. Click on Sales


6. Click on appointment


7. In required we added internal user and external contact


8. And click on save.                                                                                      

Observation:-

We see now that the internal user get the appointment synchronize in the outlook and the external contact get email.

Ask:-

We would like the appointments to synchronize in the same way for external contact as it happens for the internal user.
