We recently moved our Exchange 2003/windows 2000 server to a new Exchange 2003/windows 2003 server. We did the replication of public/system folders and moved mailboxes using the ESM. When we turned off the old server everyone that had permissions to see others calendars/inbox's etc.. could not open them anymore, except for system admin's. If we turn the old server back on it works fine. I have tried redoing the permissions when the old server is turned off, but this does not work. Did we miss a step or is there a way to fix this? We have not uninstalled Exchange on the old server yet or removed it from the group, because of this problem. Please help me.
