Hi Team.
I have a question. If install one server with Exchange Server 2016, without mailboxes, only for Relay for applications. This server need license (Activation Key) and pay for this license?
I have one server with Exchange 2010 for applications relay, but Exchange 2010 not have support. All Mailboxes in Office 365.
I am evaluating relay options, Exchange, SMTP Relay.
Thanks,
