I have 5 small customers that I host exchange for. &nbsp;From what I understand Exchange 2010 supports a mulit-tenant environment which will allow me to put these 5 companies on the same exchange server. &nbsp;Do I just install Exchange 2010 and then install SP1 in hosted mode after that? &nbsp;I am curious what the process is. &nbsp;I already have an exchange 2010 server up and running that doesn't have SP1 installed on it yet. &nbsp;Can I just install SP1 in hosted mode on this server? &nbsp;Thanks

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.
