## Search & Destroy Pre-requisites

Before using Search & Destroy in the Exchange environment, take note of the following pre-requisite knowledge.

#### Features

Feature | Description
--- | ---
Service account | This account performs the backend searches in the Exchange environment. Only one service account is necessary for the entire organization. Configure the service account as follows: Ensure that the account is a member of the Exchange discovery management group Ensure that the account never expires
Discovery mailbox | This mailbox stores the search result messages. ScanMail copies messages from the end users’ mailboxes into the discovery mailbox. Configure the discovery mailbox(es) as follows: Ensure that the discovery management group has full access permission to each discovery mailbox Assign at least one discovery mailbox to each data center in the organization
| ##### Note Trend Micro recommends that administrators do not place the discovery mailbox in Data Availability Groups (DAG) solutions. The discovery mailbox consumes more database space when used in a DAG solution.
