You can categorize archived items using Retention Categories. Settings for Retention Categories define how long the item is to be stored and whether the item can be deleted automatically at the expiry of the retention period.
Enterprise Vault comes with a single, predefined Retention Category called Default Retention Category. The Retention Period is forever.
You can create other Retention Categories as required. For example:
If you have documents that you must retain for ten years for legal requirements, you could create a new Retention Category, named Legal, with a retention period of ten years.
You might want to keep the minutes of your regular meetings for three years. In this case, create another new Retention Category, named Minutes, and give it a retention period of three years.
You select one of the Retention Categories, predefined or otherwise, to be the default for all archiving in the Site.
If permitted, Outlook users can change the Retention Category for their Exchange Server mailbox, selected folders or selected items. Because you may want to prevent Outlook users from archiving with particular Retention Categories, you can hide a Retention Category from the list of available Retention Categories. Users are still able to search for items that have been archived with Retention Categories that are now hidden.
Retention Categories cannot be deleted, because they may still be assigned to items in archives.
