How to Encrypt an Email

An email message can contain highly sensitive material that you must protect in case it is mistakenly sent to the wrong recipient. One way of keeping unauthorized people from reading your email is by encrypting it. Encrypting a message will change the email from a form that can be read to one that is indecipherable without the correct software. In order to encrypt an email, you must have a program that will do so because free Internet-based email accounts will not. Microsoft Outlook is a commonly used email software that allows you to encrypt messages.

Step

Open Microsoft Outlook and draft your message.

Step

Click the "Options" box in the "Message" tab. In the "Options" window, click "Security Settings" under the "Security" heading. This opens a "Security Properties" window.

Step

Select the "Encrypt message contents and attachments" option. After you check the box, click "OK" to close the "Securities Properties" window. Close the "Message Options" window.

Step

Send your message. Your message is encrypted.
