When Mail Security is installed on a Microsoft Exchange Mailbox server and background scanning is enabled, Microsoft Exchange creates a background thread for each message database in the Exchange store. These threads run at a lower priority to minimize the impact on other Exchange server actions. As each thread reads through the messages in the database, it detects the messages that have not been scanned by the latest definitions and scans them. This is useful if you have updated your definitions and need to re-scan the entire store with new definitions.
You can also scan the email messages that have attachments and specify which messages to scan based on the message date.
Mail Security enables the Exchange VSAPI background scanning feature. Based on the load and Microsoft Exchange's algorithms, Microsoft might interrupt the background scanning process.
