Encrypting Emails in Outlook: A Step-by-Step Guide
Outlook is a powerful email client that offers a range of features to help you stay organized and secure. One of the most significant features of Outlook is its encryption capabilities, which allow you to protect your emails from prying eyes.

What is Email Encryption?
Email encryption is the process of converting plaintext emails into unreadable ciphertext to protect them from unauthorized access. This is particularly important in today’s digital age, where sensitive information is shared online and email servers are often compromised. Email encryption is typically done using public-key cryptography, which relies on the mathematical properties of numbers to secure the data.
