We're having problems uninstalling Exchange 2003 on the first server that it was installed on
We had an Exchange 2003 environment to which we added Exchange 2007 servers and migrated all users and public folders over to the new servers.
We've managed uninstall all Exchange 2003 servers apart from one. This server was the first server to have Exchange 2003 on and when we try to uninstall we the error in the attached screenshot.
We're using domain admin accounts and they have the Exchange Full Administrator role.
