# Column Level Encryption for email attachments

# Column Level Encryption for email attachments {#ariaid-title1}

Release version: Australia  
Updated March 12, 2026  
![](https://www.servicenow.com/docs/portal-asset/ico-clock) 1 minute to read  
Secure attachments in inbound and outbound emails using Column Level Encryption.

Using Column Level Encryption for email attachments requires you to have Column Level Encryption configured on your instance. For more information, see [Column Level Encryption](https://www.servicenow.com/docs/access?context=column-level-encryption-landing&version=australia&pubname=australia-platform-security&ft:locale=en-US).

For each inbound email action, when an email includes attachments and the target record table is Column Level Encryption-enabled, the attachments added to the target record are encrypted.

If an inbound email with attachments is received from an external user who does not have access to the target table, the attachments are not added to the target record such as an
incident or case. Instead, the attachments are added to the sys_email record and the email logs.  
When you send an outbound email from a workspace with attachments encrypted on the target table, the attachments are decrypted before sending the email so recipients can access them.  
Note:  
To disable adding encrypted attachments to outbound emails, create a system property named glide.attachment.restrict_cle_attachments, and set it to true. By default, this property is set to false.
