Outlook’s emails use standard encryption out of the box. Learn how to use enhanced encryption to send more secure messages and the best Outlook alternative if you’re looking for genuine privacy.
Like most free email providers, Outlook can’t guarantee your emails are completely private. But there are ways to enhance Outlook encryption if you pay extra for an eligible premium account.
Email encryption is a process that encodes a message so that only the intended recipients of the message can read it. The message is encrypted (encoded) into an illegible string of characters called ciphertext. The only way to read it is to decrypt (decode) it into its original, legible format using a unique encryption key.
Outlook uses TLS (Transport Layer Security) to encrypt your emails by default. That means an email is secure when being sent from A to B. But TLS works only if the recipient’s service also supports it.
And once your message arrives, its security depends on what encryption the receiving server uses. As Microsoft explains(yeni pencere), “with TLS, the message might not stay encrypted after the message reaches the recipient’s email provider”.
What’s more, like most free email providers, Outlook retains the encryption keys to your messages so that it can access them.
Although Microsoft says Outlook doesn’t scan emails to target you with ads, it could still hand over their contents to third parties. In fact, Microsoft has been caught working closely with US intelligence agencies(yeni pencere), including helping the National Security Agency (NSA) evade the company’s own encryption to intercept its users’ communications.
If you want to send a more secure message in Outlook, you can enable enhanced encryption, but only if you upgrade to a premium account. You can encrypt messages using the Outlook.com web app or the Outlook desktop app.
How to encrypt an email in the Outlook.com web app
To encrypt an email in the Outlook.com web app, you need to upgrade to a paid subscription, like Microsoft 365 Family, Microsoft 365 Personal, or an eligible enterprise account.
Upgrading your account allows you to encrypt emails using Microsoft 365 Message Encryption, also known as Microsoft Office 365 Message Encryption (OME).
Encrypt an email in Outlook.com (OME)
If you have an eligible paid subscription, you can encrypt messages using OME as follows:
Click on the three-dot menu under the Outlook composer window and choose Encrypt or Encrypt & Prevent Forwarding.
Click Send.
Open an email encrypted with Outlook OME
To read and reply to a message encrypted with OME in Outlook.com, the person you’re writing to must do one of the following:
If they have a Microsoft account, they can sign in to open the email.
If they have a Gmail or Yahoo Mail account, they can choose to open the email inside those web apps or Outlook can send them a passcode to open the email.
If they have any other kind of account, Outlook will send them a passcode to open the email.
The main drawbacks to encrypting an email with OME in Outlook.com are:
Outlook sends the passcode to the same address as the encrypted email, so the message could be accessed if the account is ever breached.
The Encrypt & Prevent Forwarding option adds little extra security as anyone can always take a screenshot of the message and send it anywhere.
You can also encrypt messages in the Outlook desktop app using Microsoft 365 Message Encryption (OME), but this is only available with certain Microsoft enterprise subscriptions.
Encrypt an email in Outlook for desktop (S/MIME)
You can encrypt an email with S/MIME encryption if you have an eligible version of the app or a premium subscription.
Once you’ve enabled S/MIME, you can encrypt an email in your Outlook desktop app as follows:
Compose a new message as usual.
Choose Options → Encrypt → Encrypt with S/MIME.
Click Send.
Note that the person you’re writing to must also have S/MIME enabled with a valid S/MIME certificate. If they don’t, you’ll get the following warning with the option to send the message unencrypted:
The main drawbacks to encrypting with S/MIME in the Outlook app are:
You need to get an eligible paid Microsoft account and have an administrator enable S/MIME. It’s not a simple solution to set up and requires technical skills.
You cannot send a private message to anyone using a regular Outlook account, or any other provider without S/MIME support. You need to verify that they have S/MIME correctly set up before sending.
Unlike PGP end-to-end encryption, S/MIME has a centralized system of certificate authorities that could be compromised, though this may only matter to you if you’re at high risk of surveillance.
Open an email encrypted with S/MIME
If the person you’re writing to has S/MIME correctly configured with a valid S/MIME certificate, they can open the email as usual and it should be decrypted.
If they don’t have S/MIME enabled, you won’t be able to send them an S/MIME-encrypted email. Instead, Outlook gives you the option to send the message unencrypted.
Best Outlook alternative to send a secure email
While Outlook’s enhanced encryption options make your emails more secure, if you want to send genuinely private emails, you need to use end-to-end encryption. That way, you can be sure that only you and the intended recipients of your emails can read them.
You can use third-party plug-ins to add end-to-end encryption to Outlook. But they’re usually enterprise solutions restricted to desktop apps that require an administrator to set up.
The easiest way to send a truly secure email is to use Proton Mail, which gives you the following and more out of the box:
Easy-to-use end-to-end encryption: Any message you send to someone on Proton Mail is end-to-end encrypted automatically — no one but you and your intended recipient(s) can read them.

Open-source transparency: All Proton apps are open source and independently audited, so security experts can check they’re secure.
Proton Easy Switch: Automatically transfer and encrypt all your emails, contacts, and calendars from Outlook to Proton Mail in a few clicks.
