Redirect domain in Exchange server 2016

Dear Experts, can we redirect a mail domain to mail domain?

For example: we are using domain ABC.com for Mail Exchange server, now we want to change to the new one: XYZ.com. How can we process like this:
- Send email via XYZ.com
- Receive emails via ABC.com, then all emails will be redirected to  correspondent users in XYZ.com

You have to do it in multiple places

Recipient Policies on your Exchange server with your new domain name and apply to all the account will have default and new domain as a policy.

Public DNS change the URL to CNAME

If you have IIS and want to redirect perform IIS redirection will help.

If you are just want to redirect from one website to another not more than that then you can do site redirection in IIS pointing to new server.

I tested with ABC.com and XYZ.com, these are the results:
1. When users sent from ABC.com mailboxes, recipients see those coming from XYZ.com  ----------------------------------------> OK

2. When recipients sent emails to ABC.com or XYZ.com, those emails went to ABC.com and XYZ.com, respectively


How can we configure so that, in step 2, all emails will be forwarded to XYZ.com?  
Your help has saved me hundreds of hours of internet surfing.
