HI, <br />
<br />
We are trying to upgrade and migrate our current exchange 2010 server to exchange 2016 on a new domain. we've successfully build the exchange 2016 server and our new and old domains have a 2-way trust setup however we cant &nbsp;see the old exchange 2010 servers listed in the servers section on the new 2016 ECP so we cant start the mailbox migration. Any ideas what we may have done wrong?<br />
<br />
Thank<br />
James.

Within Internet message handling services (MHS), a message transfer agent or mail transfer agent (MTA) or mail relay is software that transfers electronic mail messages from one computer to another using a client–server application architecture. A MTA implements both the client (sending) and server (receiving) portions of the Simple Mail Transfer Protocol (SMTP). The terms mail server, mail exchanger, and MX host may also refer to a computer performing the MTA function. The Domain Name System (DNS) associates a mail server to a domain with mail exchanger (MX) resource records containing the domain name of a host providing MTA services.
