How to Send an Encrypted Email in Microsoft Outlook

How to Send an Encrypted Email in Microsoft Outlook

You’ve probably heard about email encryption and maybe you’ve even wondered when it’s necessary.

 

Confidentiality and protection of personally identifiable information (PII) are critical and if you’re sending confidential information over email, it must be encrypted to avoid falling into the wrong hands.

 

What is Email Encryption

 

Email encryption involves converting the message from readable text to scrambled cipher text. To open and decrypt the email occurs through a key. Only the recipient who has the private key that matches the public key used to encrypt the message can decipher the text for reading.

 

How much business-critical information would someone have access to if they hacked your company emails today? Contracts, passwords, customer information… Hackers who gain unauthorized access to email accounts can access attachments, content, and even take over your entire email account, without your knowledge. Imagine how much damage a hacker could cause your business if they managed to access your emails.

 

Email is secure enough for sharing basic information that doesn’t require confidentiality. But if you’re sharing anything that’s more sensitive, such as business-critical information, financial data, legal contracts, patient health information, or confidential customer information, you must encrypt your emails.

 

 

How to Encrypt with Microsoft 365 Message Encryption

 

With Microsoft 365 Message Encryption, your organization can send and receive encrypted email messages between people inside and outside your organization, whether it’s with Outlook.com, Gmail, or other email services. Email message encryption helps ensure that only intended recipients can view email content.

In an email message,

  1. Choose Options

  2. Select Encrypt 

Select the encryption that has the restrictions, such as Encrypt-Only or Do Not Forward

What does the Recipient's View of the Encrypted Email Look Like?

 

Outlook

In Microsoft Outlook the recipient’s email will contain the subject and a lock icon indicating that the message is protected. The recipient must double-click on the email to open. After Outlook verifies the recipient, the content of the email will appear.

Gmail

 

You can also send encrypted messages to recipients who do not have a Microsoft 365 account. For example, if your recipient has a Gmail account, the recipient can click on the email to open the message where it will state the email is encrypted with a prompt to “read the message”.

Clicking on this will redirect to Outlook online.

The recipient must verify the account with a one-time passcode. After verification, the recipients can read the content of the email.

Email hacking isn’t the only cause of data leaks. By encrypting your emails, you can reduce the chances of experiencing a data breach via this avenue.
