I have a client that is setting up a new Exchange 2010 server in a new
Active Directory Forest. He currently has an exchange 2007 server in a
different forest. He will keep his e-mail domain the same -e.g. acme.com
and user mailbox addresses the same -e.g. XXXX@XXXXX.COM .

He wants to have both servers up simultaneously, then migrate his mail boxes
(Some of which are rather large), one by one from the 2007 server to the
2010 server and have the 2007 server forward email for unresolved recipients
to the 2010 server until all mailboxes have been moved. I know how to do
this if both servers are in the same Forest, but that is out of the question
because he wants a new clean forest. So we are definitely not migrating ad
accounts, it has to be a new domain- client does not want to migrate,
insists on a new AD structure since it is already set up for other purposes.

So while XXXX@XXXXX.COM might get their e-mail on the 2007 server,
XXXX@XXXXX.COM will be getting his e-mail on the exchange 2010 server.

I'm worried that if we reboot the exchange server, the outlook client will
try to autoconfigure to the other server, is there a way to disable outlook
from auto reconfiguring to the other server for RPC?

If anyone has found a way to tackle this, your input would be greatly
appreciated. I have only a couple of weeks to get the resolved, he wants to
do the migration complete in 2 weeks, we want time to do testing on it
before it goes into production..

Once all the mailboxes are done migrating to the exchange 2010 server, we
will change the MX record to point to the new 2010 server and turn off the
old Exchange 2007 server.

Please post back to the group and cc a copy to my email using the

Why not just install 2010 in the 2007 org and then move mailboxes? The
standard migration process is extremely well tested and is much easier to
complete.

I guess you missed the part where I said the client wants to start with a
new clean Forest, The current Forest has be upgraded once and migrated once,
and he want to start with a new clean Forest. What you say is true, it is
just not what the man that pays the bill wants.

No, I didn't miss it. I still am not seeing a business reason for this
change, but you have to do what you have to do.

Personally, I would use a combination of ADMT and the move-mailbox.

This is a good resource:

Autoconfig is a web service I think. And you can find the app pools for it
in the IIS settings. If you stop those app pools it can stop the autoconfig,
but this is not documented as far as I know.
