setup /PreapreAD for Exchange 2010

Customer had a previous Exchange 2003 which was not properly removed. We have already removed the old Exchange 2003 server from ADSIEDIT according to MS KB. however we are now seeing this error when trying to prep domain for E2K10.

[REQUIRED] The Exchange organization is not in native mode.

Anyone have any thoughts on how to get passed this error. Currrent AD enviroment does not have a active Exchange server as they are moving from a third party hosting service back into an on-premise server.

This was the first thing we tried, thanks for the suggestions. We found some articles referencing a setup /removeorg switch however this environment does not have any 2003 servers, although I am now wondering if the command will work from an XP workstation.

Any other suggestions or thoughts are appreciated.
