How To Encrypt An Email In Outlook Option 1 Use An S/mime Certificate

One option when youre trying to figure out how to encrypt an email in Outlook is with an S/MIME certificate. In order to use an S/MIME certificate, you need to purchase a certificate, generate a CSR, go through the validation process, export the certificate and import it to Outlook.

To send an encrypted email, both the sender and recipient need to have S/MIME certificates and the sender needs to have a copy of the recipients public key. The easiest way to get this by having the recipient send you a digitally signed email before you send them an encrypted message.

The following video titled How to Install an S/MIME Certificate With Outlook on Windows 10 covers this process more in-depth. This is a very similar process for all newer versions of Outlook and most S/MIME vendors.

Once you have included the certificate on your computers keychain and configured it in Outlook, you can use your S/MIME certificate to encrypt your email.

The following process works for Microsoft Outlook 365, Outlook 2019 and Outlook 2016. You will find information on Outlook 2010 at the bottom of the section.

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.

    When Does It Make Sense To Send Encrypted Mail

    Some people still associate encryption in general with government spies and shadowy hackers who must protect their identity to escape the law. In reality, encrypted mail has become a modern necessity because billions of people around the world use email to send and receive sensitive information, such as bank account statements, business documents, and personal correspondence.

    The problem is that email users often forget or dont realize that email was never meant to play such an important role in our lives and be used to transfer sensitive information. Instead, it was intended to facilitate messaging between people who more or less knew one another, so data security and privacy werent important priorities of emails original creators.

    When you send unencrypted messages over the internet, you risk having your personal information stolen or exposed by an opportunistic cybercriminal, and only email encryption can give you the peace of mind that comes with knowing that nobody can read your messages.

    As such, it makes sense to encrypt as many emails as possible and use the most robust email encryption method available. Ideally, you want your email encryption to be applied automatically each time you send a message to eliminate the possibility of you forgetting to apply it yourself.
