Adding e-mail alias to multiple users in office 365

Question

Hi,

I'm from a Microsoft partner organization.

Recently we have started a project on Office 365. There are two domain(EX: abc.com and xyz.com). abc.com is sending domain. There are 200 users. Now we want to create alias for abc.com users using xyz.com.

How we can add alias for multiple users? Which information will have added to create the .csv file for change alias?

Thanks

Are you saying you want the users to have email addresses for both domains?

Note that you cannot just add a domain to a user unless that domain is handled by O365 Exchange.
