We have an exchange 2003 standard server. We just implemented an exchange 2003 cluster. We are trying to replicate folders from the original exchange 2003 server to the exchange 2003 cluster and for some reason it is not replicating anything. It works when we create a public folder in the cluster and replicate it to the other exchange server but we need it to work both ways. All of our public folders are in the exchange 2003 standard server and we need them to replicate to the exchange 2003 cluster.

What is the status of replication in ESM? also try this: http://www.msexchange.org/articles/Public-Folder-Replication-Troubleshooting.html
