I have an SBS 2003 installation that has exchange 2003. I installed another server using server 2008 and installed exchange 2007. I now want to uninstall exchange 2007 and have begun the process of removal. I have removed the public folders data that was on the 2008 server and am currently trying to move the public folder replicas to the 2003 exchange server. When I go to the 2003 exchange system manager and try to move the replicas I get the following error: An internal server error has occured on the server. The requested operation failed ID no: c1030af2 Echange System Manager I have also tried to use an exchange 2007 script to move the replicas but it doesn't seem to take. What do I need to do to remove this? Thanks in advance.

Can you clarify what you mean by "I have removed the public folders data that was on the 2008 server" as opposed to your other statement "currently trying to move the public folder replicas to the 2003 exchange server" ? Do the public folders currently have both servers listed as replicas?
