Is it advisable to put the domain with the same name as the public domain?

For example contoso.local is worse than contoso.com when my email will be from O365? is it a best practice?

    If you name internal / external the same you may need to do a split brain deployment.

    Hello @Angel Garcia Gomez ,

    Thank you so much for posting here.

    Microsoft strongly recommends that you register a public domain and use subdomains for the internal DNS.

    So, register a public DNS name, so you own it. Then create subdomains for internal use (like corp.example.org, dmz.example.org, extranet.example.org) and make sure you've got your DNS configuration setup correctly.

    For more information, please refer to:

    Best regards,
