We need help with exchange 2003 public folder replication with exchange 2010. Public folder replication has already been setup and exch 2010 see all updates from exch 03, but when users update public folders on exch 2010, users on exch 03 do not see them. It seems that replication works only one way. Is this true? We have about 250 users and only about 40% are moved over to the new exch 2010. Until we move the rest over, we still need our users on exchange 2003 to see updates in their public folders. Your prompt assistance is greatly appreciated.
