Use Internet mail Wizard for this purpose and the 5.5 IMC need not be shutdown.. Regards Vinoth From: exchangelist-bounce@xxxxxxxxxxxxx [mailto:exchangelist-bounce@xxxxxxxxxxxxx] On Behalf Of Allen, Christine Sent: Monday, May 21, 2007 5:44 PM To: 'exchangelist@xxxxxxxxxxxxx' Subject: [ExchangeList] Internet mail connectivity Environment: Exchange 2003, sp2 running on a windows 2003 server running in mixed mode with a Exchange 5.5 server running on a windows 2000 server. Right now just the internet connector is running on the Exchange 5.5 server. Everything has been moved over to the 2003 server. I want to install Internet mail connectivity on my Exchange 2003 server. Is there anyway I can do this while the IMC on the 5.5 server is still up an active? Or do I have to shutdown the IMC service, then install the SMTP connector on the 2003 server? The reason I want to leave the 5.5 server up is when have a fax connector that will have to be moved over as well and I want to make sure that mail flow is working internally/externally before I have the fax person install the connector. Any advice is greatly appreciated. Thanks.
