"I want a car that will protect me from driving it into a concrete pier at 70 MPH when I'm not wearing a seatbelt!" - Ed Crowley
'Way back when this question first came up, the official answer was "no". However, someone in-the-know said "try it - if you try to do the install, the legacy setup will fail". I personally have never been in this situation so I don't have an environment, real or virtual, to compare. But hey, drop Win 2003 on a desktop and see if you can do the Exchange 2003 install. All that being said - Exchange 2007 is a better product in 99% of situations. What is the problem that you are actually trying to address? Regards, Michael B.

Thanks for that. Anyway to tell, other than asking the previous technicians whom are dangling at the end of proverbial rope. -----Original Message----- From: Michael B.

Each one does it differently. Exchange 2007 uses A/D differently than Exchange 2003 did. It doesn't use some attributes that Exchange 2003 did. When Exchange 2007 was installed, it looked at A/D and determined whether it needed to update A/D, or whether it needed to "start from scratch". If it "started from scratch", then Exchange 2003 won't install, because: 1) it'll see that the schema versions don't match, and 2) security is wrong. Regards, Michael B.

'splain please. Ah are you saying that will move the mailboxes but it will still be an Exchange 2007 environment? This is going to be ugly I can tell. -----Original Message----- From: Andy David [mailto:[EMAIL PROTECTED] Sent: Thursday, February 07, 2008 5:12 PM To: MS-Exchange Admin Issues Subject: RE: Moving from E2k7 to E2k3 Not quite the same thing as what you want to do :) ________________________________ From: Stephan Barr [EMAIL PROTECTED] Sent: Thursday, February 07, 2008 6:09 PM To: MS-Exchange Admin Issues Subject: RE: Moving from E2k7 to E2k3 Found it. This is from MsExchangeTeam... "Both Exchange 2003 and Exchange 2007 mailboxes can be moved (in either direction) with the Exchange 2007 tools. Exchange 2003 move mailbox cannot be used to move mailboxes to or from Exchange 2007 mailbox server." ________________________________ From: Stephan Barr [mailto:[EMAIL PROTECTED] Sent: Thursday, February 07, 2008 5:05 PM To: MS-Exchange Admin Issues Subject: Moving from E2k7 to E2k3 I have a client that needs to move ( don't ask) from E2k7 to E2k3. Could this be as simple as installing E2k3 in the same site as the E2k7 server and moving the mailboxes? Make my day please.
