I have just upgraded 2 Windows 2000 Servers to Windows 2003, but did not know at the time that I should have upgraded the Exchange 2000 to 2003 first. I now understand that Exchange 2000 is not supported under Windows 2003, though it seems to be working at the moment.
I have installed Exchange 2003 on the second DC (there are only 2 on the domain) with a view to moving the mail store to the Exchange 2003.
Exchange 2003 is up and running and both servers appear in the ESM, however, as part of the process involving synchronization I can not get the old E2k to synch with the E2k3 server. I have added replication to all the folders but they do not appear on the E2k3 server at all, it does not seem to be doing any synchronization which I assume is because its not compatible with Windows 2003 Server somewhere?
Any help would be appreciated.
