I am trying to uninstall Exchange 2007 on a server. This server is the first Mailbox server in the Enterprise (co-existing with Exchange 2003), but not the first Exchange 2007 server. When i try to uninstall the role i get the error below. I have tried several accounts, all of which are members of Exchange Organization Administartors or Enterprise Admins. The uninstallation works on other servers. I'm stuck, any ideas? Summary: 1 item(s). 0 succeeded, 1 failed. Elapsed time: 00:01:07 Mailbox Role Prerequisites Failed Error: You must be a member of the 'Exchange Organization Administrators' group, or 'Enterprise Admins' group to remove all roles from this computer. Thanks, Jeremy

Any ideas guys? Is there a way I can turn off and manually removethis Exchange 2007 serverfrom Active Directory? Jeremy
