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
Watch Question

If I understand correctly, this is simple.

1. Register the domain XYZ.COM, and set up MX records to point to the same IP as the ABC.com.
2. Configure the Exchange server to receive email for XYZ.com and well as ABC.com.
3. Add another email address for each user, user@XYZ.com.
4. Make each user's primary email address user@XYZ.com one.

Users on Exchange can have an almost unlimited number of addresses that they receive email on, with differing domains, but only one "primary' address. The primary is the one that email is shown as being sent from.

1.Add additional accepted domain (xyz.com).
2. Create email address policy and make the new one as reply address. Update using email address policy.

Here is similar way for Exchange 2010.

Create a transport rule to send an autoreply to the sender with a text "email is changed from abc to xyz.

Yep, an autoreply rule that lets senders know to use the new domain might be a good idea. Otherwise, they will still get email from the new domain, even replies sent in response to emails to the old one. Some users of course could keep the old email address written on a bit of paper for years. You probably want to get rid of the old domain at some point.

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?
