If the migration finishes with a status of Failed, it is due to one of the following reasons:
- A fatal error occurred.
- The maximum number of failed items had been reached.
Migration errors can slow down the process, as MigrationWiz will attempt to re-migrate the item several times before logging the error. Take appropriate action based on the errors logged and resubmit the migration.
Once the migration has been successfully completed, you may resubmit the mail in Retry Mailbox Migration Errors mode.
