change domain login for exchange server 2016

Hi Experts,
I have exchange server 2016 installed and working. The exchange is connected to the domain controller: dc.companyname.com.
The exchange authentication uses the format: name.lastname@dc.companyname.com.
Is it possible to change it to use: name.lastname@companyname.com without the dc prefix?

Thanks

You can add a new domain suffix to active directory and then you will have to change all users' UPN to match this new domain.
