Question : Update Outlook 2003 profile after mailbox moved from Cross-forest Ex2K3 to Ex2K10

Hello,
Is there a way to keep away from updating all outlook 2003 profiles when mailboxes are moved to Exchange 2010 which is in another forest/organization?
Outlook 2007 and 2010 would use autodiscover to find which server to use but some users would eventually keep on using Outlook 2003 and according to MS, a manual update has to be done on profiles.
Can someone assist?

Yes Microsoft is Right.

When it comes to Outlook 2003 we will need to manually Reconfigure the Profile if Outlook 2003 is not able to Connect to the Mailbox after the Migration.

There are tools like Outlook Profile Update Tool but it does not work with Exchange 2010.
