Exchange 5.5 on Windows 2000 to Exchange 2003 on Windows 2003 migration. Error encountered in System Manager while trying to move mailboxes from 5.5 to 2003: Connecting to Source Server 0xc0070005 Access is Denied Since the Administrator (thanks Microsoft!) account did not work, the account being used: - Has full admin rights in Exchange 2003 - Service account rights at the site level in 5.5 - Log on locally to DC's - Is part of no additional AD groups Any ideas? Thank you, ...D
