In today’s digital age, email is a crucial form of communication for businesses and individuals alike. However, with the rise of cyber threats and data breaches, it’s more important than ever to ensure the security of your emails. One way to do this is by encrypting your emails. In this article, we’ll discuss how to encrypt email in Outlook, one of the most popular email clients.
Why Encrypt Email in Outlook?
Email encryption is the process of encoding email messages to protect their contents from being read by unauthorized parties. This is especially important for sensitive information such as financial data, personal information, or confidential business communications.
Outlook offers built-in encryption capabilities to protect your emails from being intercepted and read by hackers or other malicious actors. By encrypting your emails, you can ensure that only the intended recipient can access the contents of the email.

In addition to protecting your emails from external threats, encrypting your emails can also help with compliance regulations. For example, the CredSSP Encryption Oracle Remediation policy requires that all remote desktop connections be encrypted. By encrypting your emails, you can ensure that your organization is compliant with this policy.
How to Encrypt Email in Outlook
Now that we understand the importance of email encryption, let’s dive into how to encrypt email in Outlook.
Management of Native Encryption
Outlook offers two types of encryption: S/MIME and Office 365 Message Encryption. S/MIME (Secure/Multipurpose Internet Mail Extensions) is a standard for public key encryption and digital signing of MIME data. Office 365 Message Encryption is a service that allows you to send encrypted emails to anyone, regardless of whether they have an Office 365 account.
To enable S/MIME encryption in Outlook, you’ll need to obtain a digital certificate from a trusted certificate authority. This certificate will be used to encrypt and digitally sign your emails. Once you have your certificate, follow these steps to enable S/MIME encryption in Outlook:
- Open Outlook and click on the “File” tab.
- Click on “Options” and then select “Trust Center.”
- Click on “Trust Center Settings” and then select “Email Security.”
- Under “Encrypted email,” click on “Settings.”
- Click on “Choose” and select your digital certificate.
- Check the box next to “Encrypt contents and attachments for outgoing messages” and “Add digital signature to outgoing messages.”
- Click “OK” to save your changes.
To send an encrypted email using S/MIME, simply compose a new email and click on the “Options” tab. Click on “Encrypt” and then send your email as usual.
To use Office 365 Message Encryption, you’ll need to have an Office 365 subscription. Once you have a subscription, follow these steps to enable Office 365 Message Encryption in Outlook:
- Open Outlook and click on the “File” tab.
- Click on “Options” and then select “Trust Center.”
- Click on “Trust Center Settings” and then select “Email Security.”
- Under “Encrypted email,” check the box next to “Encrypt contents and attachments for outgoing messages.”
- Click on “Settings” and then select “Office 365 Message Encryption.”
- Click on “OK” to save your changes.
To send an encrypted email using Office 365 Message Encryption, simply compose a new email and click on the “Options” tab. Click on “Encrypt” and then send your email as usual. The recipient will receive a notification that they have received an encrypted email and will need to follow the instructions to view the contents of the email.
Best Practices for Email Encryption
While Outlook offers built-in encryption capabilities, there are some best practices you should follow to ensure the security of your emails.
Use Strong Passwords
One of the most basic but important steps you can take to secure your emails is to use strong passwords. This means using a combination of letters, numbers, and special characters, and avoiding easily guessable information such as your name or birthdate.
Keep Your Software Up to Date
Outdated software can leave your emails vulnerable to cyber attacks. Make sure to regularly update your email client and any other software you use for email encryption.
Be Wary of Suspicious Emails
Phishing emails are a common tactic used by hackers to gain access to sensitive information. Be cautious of emails from unknown senders or emails that ask for personal information. If you’re unsure about the legitimacy of an email, it’s best to err on the side of caution and not open it.
Use Encryption for Sensitive Information
Not all emails need to be encrypted. However, if you’re sending sensitive information such as financial data or personal information, it’s best to encrypt the email to ensure its security.
Alternatives to Outlook for Email Encryption
While Outlook offers built-in encryption capabilities, there are also other email encryption tools available. Here are a few alternatives to consider:
ProtonMail
ProtonMail is a secure email service that offers end-to-end encryption. This means that only the sender and recipient can read the contents of the email. ProtonMail also offers features such as self-destructing emails and password-protected emails.
Virtru
Virtru is an email encryption tool that integrates with popular email clients such as Outlook, Gmail, and Yahoo. It offers features such as email expiration, revocation of access, and the ability to track who has opened your email.
Tutanota
Tutanota is another secure email service that offers end-to-end encryption. It also offers features such as two-factor authentication and the ability to send encrypted emails to non-Tutanota users.
In Conclusion
Email encryption is an important step in protecting your sensitive information from cyber threats. By following best practices and using tools such as Outlook, you can ensure the security of your emails and comply with regulations such as the CredSSP Encryption Oracle Remediation policy. With the rise of cyber attacks, it’s more important than ever to take steps to secure your emails.
