Mailbox Inventory - View and manage your active email security assets - Administrator Guide - Cortex XDR - Cortex - Security Operations

The Mailbox Inventory provides centralized asset visibility for all mailboxes managed under the Email Security module. Connected to the Unified Asset Inventory (UAI), this dedicated page displays all active mailboxes in a single, comprehensive table. From this view, you can use dashboard widgets to see a high-level breakdown of your assets and filter the table by specific mailbox types (such as user, room, or shared) to manage your email environment.

When you filter using either the widgets or the table, both the widgets and the table are updated.
