In today’s digital landscape, the idea of privacy often seems elusive. However, applications like Microsoft Outlook provide robust security features to keep your information safe during transit. One such feature is end-to-end encryption, ensuring that only the intended sender and receiver can access the contents of your emails. If you’re using Microsoft Outlook, you might wonder: how can you easily encrypt your emails to maximize your privacy?
Before diving in, it’s important to note that email encryption through Outlook is exclusively available for users with a Microsoft 365 subscription. Dubbed ‘Pureview Message Encryption,’ this feature is user-friendly and straightforward to implement.
Encryption in Outlook is confined to the Windows and macOS desktop versions, as well as the web app. Unfortunately, the mobile apps for Android and iOS do not support this feature.
1. Encrypt Emails in Outlook App via Options Tab
Encrypting your emails in the Outlook desktop or web app is a breeze. Remember, it isn’t enabled by default, so you’ll have to activate it each time you send a confidential message. Follow these simple steps:
