- We have email hosting via Google with the domain name company.com.
- We also have an Active Directory domain with the same namespace.
- We provide hosted services for small businesses and host their email on an Exchange server on the company.com domain. We use aliases to give them a email@example.com e-mail account.
Our clients can not send email to us at firstname.lastname@example.org because the internal DNS server thinks it knows how to resolve that name but is unable to resolve. Is there a way to resolve this issue either via DNS or Exchange Server?
