Can't uninstall Exchange2003 after migrating to Exchange2010. One or more users currently use a mailbox store on this server.

If I try to uninstall Ex2003 via System->Add/Remove Programms->Microsoft Exchange, I get following error message:
"One or more users currently use a mailbox store on this server. These users must be moved to a mailbox store on a different server or e-mail disabled before this server can be uninstalled"
I've already searched for AD users with old exchange attributes, but nothing found.
Could you help me?

Have you tried this? I know I've had to do this twice.

yes, I did, but I see all users have the exchange2010 as a exchange home server.

Go to ADUC and Custom Search and put this in

(&(objectClass=user)(objectCategory=person)(msExchHomeServerName=/o=EXCHANGEORGNAME/ou=First Administrative Group/cn=Configuration/cn=Servers/cn=SERVERNAME))

If you find any account simply go with Delete Mailbox or Remove Exchange Attributes

what you need to run is

ldifde -d "DC=ROOT,DC=COM" -f c:\output.txt -r "(&(objectCategory=person)(objectClass=user)(msExchHomeServerName=/o=ORGANIZATION NAME/ou=ADMINISTRATIVE GROUP NAME/cn=Configuration/cn=Servers/cn=SERVER-NAME-TO-REMOVE))"

Open in new window

of course replace the variables by the correct entries.

once you do check the output.txt file
