Error
Cannot migrate to a Destination mailbox equal to the Source mailbox: The Source mailbox has the same email address as the Destination.
Cause
The Source mailbox has the same email address as the Destination. In addition, the Source email system is the same as the Destination email system.
MigrationWiz detects this condition and issues an error to avoid migration preventing the accidental migration of a mailbox to self (and so the duplication of all content).
Resolution
Ensure that the Source and Destination mailboxes are different by editing connector or mailbox properties. Consider MigrationWiz supports scenarios where the Source and Destination mailboxes have the same email address. However, the Source and Destination systems cannot be identical.
