Hi DoohickyMicky,

 

The easiest way would be to add the example.com domain as an accepted domain to your Exchange Server. After adding it as an accepted domain, you can change the default email address policy to make the example.com domain the primary domain and apply the policy to everyone (https://learn.microsoft.com/en-us/exchange/email-addresses-and-address-books/email-address-policies/email-address-policies?view=exchserver-2019) After you applied the new settings, everyone will have a Primary Email address of email address removed for privacy reasons. 

 

If your send connector is scoped to only whatever.example.com, you should add example.com as well. If your send connector is not scoped, you should be fine and your email will be send to your ISP.

 

To make sure that it's not marked as Junk, you should add an SPF record with the external ip address of your mail server to the public DNS of example.com.

 

I hope this helps.

 

Regards,

Ruud
