The discovery feature of Archiving and Discovery is used to search across live* and archive mailboxes for email messages and attachments. The discovery tool can be run from the administration console and the results are copied to a target mailbox that you specify.
You can search outgoing and incoming email by date, from, to, cc, subject, keywords, and attachments. The advanced search feature can be used to quickly create a query to search by name, dates and time ranges, distribution list, aliases.
Target mailboxes are created to receive discovery search results. You can organize your search results by creating different target mailboxes or by creating individual folders within a target mailbox for each search you run.
X-zimbra-Source header information is added to each message header that is copied to the targeted mailbox. This header label includes the account ID, the account name, and the server that the account resides on.
