I am in the process of migrating my users off an Exchange 2003 server to an Exchange 2010. Many of my users that have been migrated to the new server cannot see objects in the public folders any more. They can still get into the folder, but it's like it's empty. Users that have not been migrated can still see object in the public folders. Could it be a replication issue? If so, how do I check that? I have made sure that replication is set between the old and new server (I think) but I am not sure the replication is happening. Advice anyone?
