Why Email Encryption is Important

Email encryption is essential in safeguarding information. Cybersecurity Ventures predicts that cybercrime will inflict damages totaling $10.5 trillion annually by 2025. With such a threat landscape, the need for encrypted communication is clearer than ever. Encryption ensures that even if emails fall into the wrong hands, the content remains indecipherable, offering a critical layer of protection for companies handling proprietary data, financial information, or personal details.

How to Encrypt Email Outlook

If you rely on Outlook for business communication, understanding how to encrypt your email is crucial.

Using S/MIME Encryption

S/MIME (Secure/Multipurpose Internet Mail Extensions) is an industry-standard for sending secure emails. Here's how to set it up:

1. Obtain a Digital Certificate: First, secure a digital certificate (or digital ID) from a trusted certification authority. These certificates bind your identity to a public key.

2. Install the Certificate: Once acquired, install this certificate in your Outlook. Navigate to the 'Trust Center' in Outlook's 'Options' menu, then click 'Email Security', and import your certificate.

3. Encrypt Your Email: When composing a new message, go to the 'Options' tab and select 'Encrypt'. This ensures that your message is sent as encrypted, requiring the recipient's private key to decrypt.

S/MIME is an effective solution, but both sender and recipient must configure their systems properly, which might pose initial setup challenges.

Leveraging Office 365 Message Encryption

Office 365 Message Encryption (OME) offers an excellent alternative for organizations using Microsoft 365 services, simplifying how to encrypt email Outlook messages.

1. Admin Configuration: Administrators can set up transport rules within the Microsoft 365 admin center to automatically encrypt emails based on specific conditions.

2. End-User Process: When composing a message, users simply select an 'Encrypt' option within the Outlook application. Without the need for additional certificates, OME leverages Azure Information Protection for seamless integration.

Office 365 Message Encryption integrates easily with existing Microsoft ecosystems, making it a practical choice for businesses already entrenched in the Microsoft environment.
