In today’s digital landscape, email encryption has become a critical component of safeguarding sensitive information and maintaining secure communication channels. Microsoft 365 offers a comprehensive solution through Office 365 Message Encryption (OME), empowering users to protect their emails from unauthorized access. This guide will provide you with a step-by-step approach to encrypting your emails, configuring encryption settings, and adopting best practices for optimal email security.

Practical Example of Email Encryption
Sending an Encrypted Email Internally and Externally
- Compose the Email:
- Open a new email in Outlook.
- Address it to a colleague (internal recipient) and perhaps a Gmail account (external recipient).
- Enter a subject and body text.
- Encrypt Only:
- Click on “Options,” select “Encrypt,” and choose “Encrypt only.”
- Send the email.
Internal (Colleague’s Mailbox):
- The email appears with a padlock icon indicating encryption.
- The colleague can open and read the email without issues.
External (Gmail):
- The recipient gets a notification to verify their credentials to read the encrypted message.
- Do Not Forward:
- Compose a new email.
- Address it to a colleague and your Gmail account.
- Select “Options,” then “Encrypt,” and choose “Do not forward.”
- Send the email.
Internal (Colleague’s Mailbox):
- The email is encrypted and cannot be forwarded or printed by the colleague.
External (Gmail):
- The recipient can read the email but cannot forward or print it.
- Confidential – All Employees:
- Compose another email.
- Address it to a colleague and your Gmail account.
- Select “Options,” then “Encrypt,” and choose “Confidential – All employees.”
- Send the email.
Internal (Colleague’s Mailbox):
- The email is encrypted and can be forwarded and printed within the organization.
External (Gmail):
- The recipient receives a notification that they do not have permission to view the message.
Office 365 Message Encryption (OME)
Office 365 Message Encryption (OME) is a powerful tool that takes email security to the next level. With OME, you can send encrypted messages to anyone, regardless of their email provider. Recipients can easily read encrypted emails by using a one-time passcode or signing in with their Microsoft account.
OME seamlessly integrates with Microsoft 365, providing a user-friendly experience for both senders and recipients. It ensures that your sensitive information remains protected, even when communicating with external parties.
Configuring Encryption Settings in Microsoft 365
To maximize the effectiveness of email encryption, it’s essential to configure your encryption settings properly. Here’s how you can do it in Microsoft 365:
- Admin Center: Navigate to the Microsoft 365 admin center.
- Security & Compliance: Access the Security & Compliance center.
- Data Loss Prevention: Under the “Data Loss Prevention” section, select “Policy.”
- Create a Policy: Create a new policy that applies encryption to emails containing sensitive information. Customize the policy based on your organization’s specific requirements.
By configuring encryption settings, you can automate the encryption process and ensure that sensitive information is consistently protected.
Sending and Receiving Encrypted Emails
When sending encrypted emails, keep the following best practices in mind:
- Verify Recipient: Double-check the recipient’s email address to ensure accuracy.
- Use Clear Subject Lines: Avoid including sensitive information in the subject line, as it may not be encrypted.
- Inform Recipients: Let recipients know that they will receive an encrypted email and provide instructions on how to access it if necessary.
Recipients of encrypted emails will receive a notification with instructions on how to read the message. They can use a one-time passcode or sign in with their Microsoft account to decrypt the email and access its contents.
Troubleshooting Common Encryption Issues
If you encounter any issues with email encryption, consider the following troubleshooting steps:
- Check Settings: Ensure that your encryption settings are correctly configured and aligned with your organization’s policies.
- Update Software: Make sure your email client and Microsoft 365 applications are up to date to avoid compatibility issues.
