What tools are available to migrate mailboxes from an Exchange 5.5 sp3 org to a mixed E5.5sp3/E2k org? The mixed org was originally an NT4 domain and E5.5 servers. We created a new Win2k domain and we joined the E5.5 org and installed our E2k server into this org. We are using the interorg replication utility to replicate Public folders and free busy times and are using the ADC to provide a GAL and mail routing Regards Leo
