Key notes
Have you ever sent an email to the wrong person or meant to send it to one person but mistakenly sent it to someone else? For example, you may want to send confidential information over email, but you don’t want your message to be easily accessible.
To prevent unauthorized access, you can use Outlook to encrypt the message. Read on to find out how to send secure email in Outlook.
Does Outlook offer secure email?
Outlook offers secure email features. Most people are familiar with the basic security features, such as the ability to password-protect emails and prevent recipients from forwarding or copying messages. But there’s more to Outlook security than that.
How can I send a secure email in Outlook?
1. Individual email messages
Outlook users who want to send S/MIME-protected emails must install a S/MIME certificate on their computer and configure their Outlook settings accordingly.
2. All emails
What does encrypting an email do?
Encrypting an email is a way to protect the contents of your message from being accessed by others. If you’re sending sensitive information over email, it’s essential to ensure that no one but the intended recipient can read it.
The encryption process occurs in two steps. First, you need to encrypt the message so that nobody can read it without the correct key. Then, it would be best if you decrypted it with the right key. So, how do you open an encrypted email in Outlook?
You’ll see a lock icon next to the sender’s name if you receive an encrypted email. You can open the email by clicking the lock icon. You will then be prompted to enter the security key to reveal the content of the email.
Encrypting your emails doesn’t mean you send them in secret code. It just means that only the person with the correct decryption key can open them. Now that you know encryption, you may wonder:Where is my Send Secure button in Outlook?
When you send a new email message, you can find the Send Secure button under the File option at the top left corner.
And that’s how to send emails using Outlook securely. Should you encounter any issues, such asOutlook failing to open in Windows 11, we have a dedicated guide for you.
