Moving mailbox from 2010 back to 2003

Hi Experts,

I've got a problem! I'm working on moving mailboxes from Exchange 2003 to a new exchange 2010 server. They use OWA and I figure I can't have OWA running through the gateway to two different servers at the same time so I thought I'd move the OWA services last.

Guess what? I went and moved one of the mailboxes that uses OWA to the 2010 server so now I'm trying to move it back so that user can still access their email through the web.

I undersand I need to do this "downgrade" via the Exchange PowerShell, not the Management Console so I have created the following command to see "whatif" to make sure I'm ready to move the mailbox back to to 2003. The problem I get is that the mailbox database does not exist. Here's the command and resulting message:

[PS] C:\Windows\system32>New-MoveRequest -Identity 'jbeakley@company.com' -TargetDatabase 'S2K3EXC\First Storage Group\Mailbox Database' -WhatIf

Mailbox database "S2K3EXC\First Storage Group\Mailbox Database" doesn't exist.
+ CategoryInfo : NotSpecified: (:) [], ManagementObjectNotFoundException
+ FullyQualifiedErrorId : ED66F62B

To make sure I had the 2003 DB name right, I took it from how it is referred to in the mailbox move process inside the Exchange 2010 Management console.

I tried referring to it this way too and got the same result:
"S2K3EXC\First Storage Group\Mailbox Database (S2K3EXC)"

Anyone know what is going on?

Thanks,

Paul

You are wrong that you have to use PowerShell. You can just move the mailboxes back to Exchange 2003 using the Exchange 2010 Management Console. During the wizard simply select the Exchange 2003 database to move it to. Once it has been moved you cannot manage the account or mailbox with Exchange 2010 tools.

Hi Simon,

I don't even see a way to run the wizard when I select a mailbox that has already been moved to 2010.

Thanks,

You were absolutely right Simon both on the fact that I CAN use the GUI to move the mailbox back to EXC 2003 AND the reason I couldn't get a new Local Move Request for that mailbox/user was indeed because I had not cleared the last move request.

Thanks very much!
