MORE INFORMATION
This behavior occurs if the Migration Wizard cannot log on to one or more mailboxes successfully. If the Migration Wizard cannot log on to a mailbox, the Migration Wizard retries the logon attempt for 60 minutes before it continues to the next mailbox. For example, if the Migration Wizard cannot log on to 10 mailboxes during the migration process, you may experience a delay of up to 10 hours before the mailbox migration process is completed.
