Removing Exchange 2003 & Postmaster - 27.Jan.2012 1:52:02 PM

I'm down to my last step of the migration from Exchange 2003 to 2010 which is uninstalling the 2003 server.

When I attempt to do this, I get the error message:
"Setup encountered an error while checking prerequisites for the component "Microsoft Exchange": 0X80072030 (8240): There is no such object on the server"

My research has led me to the "postmaster" account being the problem, so I've followed the MS KB 283089 by assigning a new account via ADSIEdit, but it's still not working and giving me the same error.

The thing that's unique about my situation is that back when Exchange 2003 was installed I wasn't working here and I just found out that according to AD via ADSIedit, I see that the postmaster account was the default Administrator account.

This account in AD shows that it's mailbox is located on Exchange 2010 but when I go into Exchange 2010 via EMC the account doesn't show in the Mailbox view.

I also found that at one point a distribution group was created for "postmaster" so that messages would go to multiple people in IT. I deleted this distribution group and manually assigned the smtp address of postmaster@company.com to the existing Administrator account and I still get the error.

So, I decided to follow the MS KB by choosing another user already on Exchange 2010. I removed the postmaster smtp address from Administrator and assigned it to another account and changed that account in ADSIedit, but still no go...same error.

I appreciate any ideas on what to do to resolve this problem, thanks.
