You can help users identify messages from outside your organization by adding text to which of the following options?

To help users identify messages from outside the organization, adding text to various parts of an email communication is effective. The correct answer encompasses all options because each has its own purpose and visibility.

Adding text to the message subject can explicitly notify recipients that the email is from an external source. This is often the first thing users see, so it can serve as a warning before they even open the email.

Inserting text into the message body can provide additional context or instructions, reminding users to be cautious about the email's content, especially if it requests sensitive information or contains links.

Modifying the message header can also be beneficial, as technical users may look at headers for metadata about the sender and the route taken by the message. By including indicators in the header, recipients can better recognize potentially suspicious external emails.

Using all these methods in combination offers a comprehensive approach to engage users in safe email practices, reinforcing the idea that vigilance is necessary when dealing with external communications. Therefore, combining text changes in the subject, body, and header serves to enhance awareness and security across multiple touchpoints.
