In my scenario I am running two Forests With a Two Way Trust. The old Forest contains Exchange 2003 SP2 and the new Forest contains Exchange 2010 SP1.

I prep the mailboxes for move using the cmdlet on Exchange 2010 using the Prepare-NewMoveRequest script, and then initiate a New-MoveRequest script for the user mailbox and everything runs smoothly. The mailbox moves into Exchange 2010 and works fine.....

The issue: Can I? or How do I get the Outlook 2007 client to automatically update the server path from the Exchange 2003 server to the Exchange 2010 server in the new forest?

Any help is appreciated!

Hi Busbar! Thanks for the reply....

The clients still remain in the old Forest until we migrate them in our next step of this migration process....

After moving the mailbox, I converted it to a Linked Mailbox as well so their normal credentials would login on to the mailbox. The account "OLDDOMAIN\user" does login with my testing via OWA on the Exchange 2010 server.

The trick is getting the client to re-path since the crednetials work..... That is where I am hitting a brick wall... Ha Ha!

Thank You,

Ed

ok,

you can use the export-autodiscover cmdlet to export the autodiscover and simulate resource/account forest until you finish the migration, once migrated users will use autodiscover in the new forest and you will fine
