Primarily for public companies or those companies working for public companies subject to formal data retention policies, ZAD is an optional service available in the 01.com shared hosting environment on a per mailbox basis, both for our business and personal services, and as an optional license to companies with dedicated, or their own servers, particularly useful for legal compliance (SOX, HIPAA...) and other organizational policy fulfillment, Zimbra Archiving and Discovery (ZAD) stores mail for each mailbox on which it is enabled in an archived format that is not viewable by users without Zimbra administrative privileges.

The archived mailboxes are then searchable, across all of the mailboxes and their data, including attachments and headers, and the results are available in an Ajax web interface that enables viewing by conversation across an entire organization.  As of version 5.0.x, you must have super admin privileges to search the archives, so direct access is not available to customers in the shared hosting environment yet, and requests for searches must be made through our ticketing system, conducted by 01.com, and the results returned.  We expect the ability to search ones own archives to become available to users in the shared environment once the feature "delegated administration" is complete, as early as later in 2008, with the introduction of Zimbra 5.5.

Note that Zimbra Archiving and Discovery may be used independently by organizations looking for a cost-effective system to archive their company's mail. Please also note that for clients using ZAD in our personal or business hosting service, the resulting archives are charged for monthly on a usage basis, as opposed to quotas, which are charged for monthly on a reserved basis.
