An often-over-looked tool within the Intradyn Archiver is Search Exclusion.
This feature allows an admin to input a select set of addresses, and effectively hide the communications involving those accounts from being viewed. The account in question can be placed in a search exclusion, preventing their communications from being viewed by anyone who isn’t granted explicit override permission to do so. This allows you to remain in compliance with legal regulations, while also maintaining an element of privacy until specific actions are taken.
