have an existing exchange 2007 server that is the authoritative exchagne server for a couple domains, currently we have an icewarp server also in the AD forest handling mail for another email domain. &nbsp;We are replacing the icewarp server with exchange 2010. So what happened was after installing exchange 2010, it pulled all the mailboxes from the 2007 server as well. &nbsp;I added all the current icewarp users to exchange. Now anyone from the 2007 server can't send mail to the 2010 server, i assume because its trying to send through the 2010 server yet? &nbsp;we aren't ready to go live yet on the 2010 server, how can i keep mail going to icewarp until ready? &nbsp;remove the mailboxes of those users for the time being?<br />
<br />
thanks
