Arctera Insight Archiving item properties for use in custom classification policies

Last published : Apr 17, 2026
When Arctera Insight Archiving indexes an item, it populates the item's metadata properties with information about the item. Some examples of this information include the display name and email address of the message author, the archived date, and the file size of the item.
Indexed items can have a large number of properties, but only a subset is relevant for classification purposes. Arctera Insight Archiving passes this subset of properties and their associated values to the Arctera Insight Classification for use in classification. When you create a custom Arctera Insight Classification policy you can enter the names of these properties in the custom date, custom number, or custom string fields, when you define the policy conditions.
