Arcserve Backup Creates Duplicate Messages When Restoring Data

Valid on all Exchange Server systems.

Symptom

Arcserve Backup duplicates messages when you restore a document to the same location using the Overwrite conflict resolution option.

Solution

This is expected behavior. When you restore a message, a new message ID is created and assigned to the message. Consequently, if you restore data from on backup multiple times, you will see duplicated messages.
