To prevent issues with large email messages, the system enforces configured limits on
the maximum allowed email body size, total attachment file size, and number of attachments per
email.

An email or attachment that exceeds the system capacity may not be processed as expected. To
ensure that your emails and attachments are processed as expected, you can configure properties
that limit the size of emails and attachments.
* **[Message body size limit properties](https://www.servicenow.com/docs/Mj7RC~9pEz4sJuOzJjtUcg)**   
  Add properties to control the maximum email body size allowed for inbound and outbound email messages.
* **[Attachment limit properties](https://www.servicenow.com/docs/flIZprOehB_fNmQjpdUcFQ)**   
  Several properties control email attachment limits.
