Hi Michael, Thanks! I want to leave the first Exchange 2000 Server on the Windows 2000 machine in place; the Exchange 2003 Server on the Windows Server 2003 Server would be the *second* Exchange Server on the network in the same domain. I would use the "Exchange Tasks" move mailbox feature on the Exchange 2000 server to move some of the user mailboxes to the second Exchange Server (which would be running Exchange 2003). The goal of this exercise is to provide enhanced OWA and OMA support for the users who's mailboxes I move to the second Exchange Server, since from what I understand, if I made the new Exchange Server a Front-end server, I would not benefit from enhanced OWA and OMA support, as these enhancements are part of the actual message store. At the same time, I want to leave some mailboxes on the existing Exchange 2000 Server.

The answers are: yes, yes, and yes. If upgrading, then Exchange needs to be upgraded before Windows. If clean install, Windows needs to be installed before Exchange. :-) -----Original Message----- From: Robert Abela [mailto:robert@xxxxxxx] Sent: Wednesday, May 12, 2004 11:22 AM To: [ExchangeList] Subject: [exchangelist] RE: Exchange 2000 and 2003 in Same Domain http://www.MSExchange.org/ Hi Tom, You want to install a new exchange server on a new machine or you want to upgrade the current installation?

If so, can I move user mailboxes from the Exchange 2000 Server to the Exchange 2003 Server? If so, can users who have mailboxes on the Exchange 2003 Server access the enhanced OWA and OMA services on the Exchange 2003 Server? Thanks!
