A customer A move his domain to our infastructure but he is not started to use it yet.He is using his mail server until finish decomision . &nbsp;Another customer B in our Exchange infastructure wants to send email to customer A but the problem is that email from customer A stays inside our Exchange because the mail users exist in Exchange. How i can bypass this so the emails go to the email server of the customer in his premise installation &nbsp;? <br />

Hosted Exchange 2013 - Disable Domain of a Tenant

Exchange is the server side of a collaborative application product that is part of the Microsoft Server infrastructure. Exchange's major features include email, calendaring, contacts and tasks, support for mobile and web-based access to information, and support for data storage.

Exchange

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.
