I am trying to figure out if there is a way to set up an Exchange server with the following criteria:
Background - our company is changing names and adding global partners.
Many addresses @domainA.com will be local users that connect to their existing mailboxes on the server.
Other addresses @domainA.com will be users who are running other mail services (not necessarily Exchange servers) located remotely in other parts of the world. These may be their own mail servers or a service provider like an ISP or Google Business Apps.
Internal and External email should be delivered to the local users where appropriate, but should be forwarded to the destination mail server for delivery for those users who are not members of the local domain.
Everyone should be able to send and receive from their @domainA.com address.
Is it possible to run this kind of set-up, and if so, what features or setup do I need to research?
Thank you in advance.
