How To Send A Fully Encrypted Email In Outlook
Microsoft Outlooks email encryption services arent as secure as you may believe. This is because Outlook encrypts email using S/MIME and Office 365 message encryption, which both rely on the sender and recipient having it enabled.
You may not be protected when emailing a recipient who uses an email platform that doesnt support S/MIME or Office 365 message encryption. Free webmail users such as clients on Gmail, Yahoo, and iCloud often wont have the functionality needed for robust email encryption.
In 2019, cyber criminals hacked webmail client Outlook.com and gained access to sensitive private information, including email subject lines, folder names, contact lists, and some email content. Using end-to-end encryption is the only way to make sure that your Outlook email messages and attachments are entirely secure, both while in transit to your recipient and sitting at rest in an inbox.

How To Encrypt Email In Outlook
Just like Gmail, Outlook.com uses TLS encryption to protect the connection with a recipient’s mail service provider. The problem with TLS is that it protects messages only while they’re in transit and doesn’t guarantee that they’ll stay encrypted after they reach the recipient’s service provider.
Microsoft implemented its own Outlook email encryption system, which ensures that your messages always remain encrypted and don’t leave Microsoft’s servers. Outlook email encryption is available to Office 365 Home or Office 365 Personal subscribers, and it could hardly be any easier to use.

Outlook.com users can read encrypted email messages just like regular messages. The users of third-party mail services receive a message with instructions for how to read the encrypted message.

S/mime Encryption For Outlook
S/MIME encryption can be tricky to configure namely because your intended recipient will need to be using an email service that supports S/MIME and have it set up and ready to rock. This is pretty unlikely. S/MIME requires that you acquire a certificate to validate your identity and, of course, requires that your recipient have one, too. It’s a lot of legwork, and to make matters worse, S/MIME can be rendered totally ineffective if an encryption key gets lost or falls into the wrong hands.
- All in all, S/MIME is probably only going to be used effectively by folks whose workplaces already have it set up.
OME Encryption for Outlook
With Office 365 Encryption, you won’t need any certificates to send encrypted messages. You will need a valid subscription, however, which can set you back a pretty penny. Whilst sending encrypted emails via OME is straightforward, your recipients will have a bit of work to do to access the message. OME requires recipients to either sign in to an Office 365 account or confirm their identity via a single-use password, sent as a code to a mobile device or email account. Some recipients won’t have a problem with this, whereas others may struggle to understand what’s asked of them, or be unable to presently confirm their identity.
- Although, OME can successfully send encrypted emails to recipients using email clients other than Outlook!

Additional Things To Know About Sending Encrypted Emails In Outlook
If youve decided that you want to set up S/MIME for your Outlook account and secure your email this way, there are a few other things to note before you do so. Here are a few essential things to keep in mind when setting up S/MIME on Outlook:
- You need Internet Explorer 9 or later to use this feature, both as a sender and recipient.
- S/MIME encryption applies only to recipients within your organization. Anyone else that receives an encrypted Outlook email wont be able to decrypt it.
- If at least one of your recipients has a S/MIME certificate, Outlook will send the encrypted email to all intended recipients, regardless if somebody else doesnt have this feature enabled.
- If you send an unencrypted but digitally signed email to a recipient outside of your organization, they will be able to read the content within it, but may not be able to verify the signature.

Why Is Email Encryption Important
Email encryption is important because it protects you from a data breach. If the hacker cant read your message because its encrypted, they cant do anything with the information. Since 2013, over 13 billion data records have been lost or stolen. The average cost of a data breach in 2018 is $3.86 million. This number has grown by 6.4% since 2017. Data breaches can be costly because they take a while to identify. In 2018, the mean time to identify a breach was 197 days and the mean time to contain it was 69 days. Email encryption is a preventative measure you can take to avoid being part of a cybersecurity statistic.
How Do I Send A Secure Email In Outlook
Sending an unsecured email can be likened to writing sensitive information on a sticky note and leaving it on someone else’s desk: anybody can intercept and share that information. Fortunately, there are ways to ensure your emails are safe from the prying eyes of hackers through encryption, meaning your message no matter how sensitive is seen only by the intended recipient.
An encrypted message is changed from plain text into ciphertext, which is unreadable and remains that way until it reaches its destination. That means that even the most determined hacker won’t be able to gather sensitive information from the email. Once it arrives with the intended person, the encryption is removed, provided their identity has been confirmed.

- 6 minute read
Email encryption is the process of disguising the content of your email messages to protect them from being read by unwanted parties. Sensitive information such as social security numbers, passwords, login credentials and bank account numbers are vulnerable when sent via email.
When encrypting emails, its important to encrypt all of them, not just the ones with sensitive information. If only some of your emails are encrypted, it is a red flag for a hacker and could make your inbox even less secure. They will only have to hack into a few emails rather than sift through hundreds to find data they can use. We explain how to encrypt emails on multiple providers and summarize our tips in an infographic.
