I'm in the process of migrating from exchange 2k to 2k3.
I went to each public folder, including the system folders, and added the new 2k3 server on the replication tab.
I did this last night before I left work. Today, when I check the status, they all say "Locally modified" on the new 2k3 server, and "In sync" on the old 2k server.
I checked the public folder store on the new server, went to public folder instances, and none of the folders are showing, not even one.
Also, the public folder database size has NOT increased on the new 2k3 server.
The public folder database on the old 2k server is about 13GB.
The Public folder Store replication interval is set to Always run.
