In a Microsoft Exchange 2007 environment, the deduplication process with which Enterprise Vault minimizes the number of duplicate items that it archives does not work as expected. When Microsoft Exchange 2007 journals an item that has both individual recipients and one or more distribution lists, Enterprise Vault may archive it several times - and consequently the Journaling Connector may fail to capture it correctly.
This issue arises because of a change in the way that Microsoft Exchange 2007 deals with items that are addressed to both individual recipients and distribution lists. For more information, see the following article on the Symantec Support website:
