Moving Exchange Mailboxes

Microsoft Exchange mailbox
I'm using Exchange 2007 on a 2003 server. We have a mailbox database about 26 GB on our D: The D: only has 1.75 GB of space left. Exchange tells me the database has 3GB of whitespace which I'd like to reclaim. I know I can do this using an eseutil defrag, but it would require the mailbox to be offline, which isn't an option unless I can find some way to automate it during the night. Another trick I read about is to create another database and move all mailboxes over to that and then you can delete the first database and reclaim the space without having to take anybody offline for a long period of time. Problem is, my C: only has 8 GB of free space and my D: only 1.75. I can easily map drives to other non-exchange servers that would have suffient space. I'm wondering if there's a trick where I could move mailboxes over to another non-exchange server temporarily so I can delete the database, create a new one, and move them back. Or even some automated way to run eseutil. I'm open to any suggestions or ideas.

Thanks. We'll let you know when a new response is added.

In earlier version fo Exchange there was a tool called ExMerge moving mail to a .pst file.

With Exchange 2007/2010 you can use Powershell, the script for moving a database to a.pst is:

Get-Mailbox -database “Mail\Mailbox Database” | Export-Mailbox -PSTFolderpath \\mail\PST

Your .pst is very large, I would build another 2007 Exchange Server and move the mailboxes across, then move them back once you have re-build the exchange server.

    I really don't have the option of building another exchange server. I need to keep down time as low as possible. Does anyone know a way to trick exchange into thinking a mapped drive is an actual drive on the server itself so I can create and mount a mailbox database on a mapped drive?
