Moving Exchange 2007 mailboxes to different domain

We have a new customer that no longer wants to host Exchange and wants to move to our Exchange environment.  Is there a good way of doing this or is it not possible?

How do you go about exporting mailboxes?

It's straightforward enough if you have access to the Exchange server they are on at the moment:

If you can't access the Exchange server, then manually on each PC use Outlook's Import/Export functionality to export the mail to PST.

Then create the accounts on new Exchnage server and import mailboxes to user accounts.

the quickest way is to use exmerge. It will run directly from the Exchange mailstore without having to manually do individual users from outlook. Read the readme.txt though. you need to create a user account and you need to run the application from a specific location. best of all its free.
Google 'exmerge'

exmerge is not supported with Exchange 2007, if you can, I'd advise using Export-Mailbox. There are hacks to get exmerge working but better to use Export-Mailbox as this is the supported method.

So if you create a trust between the two domains, how do you go about seeing that other domain and exchange mailboxes in Exchange Mangement Console to export/import them to the new domain and mailbox server?

I wouldn't look to create a trust, I'd export to PST and then import to Exchange if you can, far easier.

Needs to be a 32bit PC with Outlook 2003 SP2 or above and Exchange managment tools installed.

I already had those requirements.  Found out if you type in fixmapi right from the command prompt that resolves the issue and exports the mailbox.

You will need full mailbox access with the account you are using to run the Export-mailbox as well.
