I am running Exchange 2007 sp1. I am retiring the old mailbox server and moving the function to new hardware. I moved the mailboxes, changed the public folder store settingon the new mailbox databases to point to the new server. I ran the MoveAllReplicas script included with Exchange 07. Everything looked fine until I tried to uninstall Exchange on the old server. I was informed I still had PF replicas in the old public folder DB and I couldn't uninstall Exchange until I fixed that. I checked in EMC and the EFORMS REGISTRY, OFFLINE ADDRESS BOOK and SCHEDULE+ FREE BUSY system public folders have no entries on the Replication tab. When I try to set one, I get the error:--------------------------------------------------------Microsoft Exchange Error--------------------------------------------------------The following error(s) occurred while saving changes: set-publicfolderFailedError:Cannot save the object '\NON_IPM_SUBTREE\EFORMS REGISTRY'. Please make sure that you specified the correct Identity and that you have the necessary permissions to save it. MapiExceptionNotFound: Unable to set properties on object.
