As part of our integrated investments in data protection, we’re launching new, rich capabilities in Office 365 message encryption that protect and control your sensitive emails. These enhancements are specifically aimed at helping you better protect your sensitive email communications without hindering your users’ productivity and ease of collaboration with those inside and outside your organization.
Office 365 Send Secure Email
Read below to find out more about what we offer and how you can get started.
Office 365 Email Encryption
Help reduce the risk of accidental or malicious data loss by making it easy for your users to protect and read confidential emails.
In previous versions of Office 365 Message Encryption, users could encrypt their messages using specific keywords in the subject or body of the message. While this is a powerful feature for organizations to automatically encrypt sensitive email, it presents an obstacle for end users who want to send ad hoc encrypted messages.
Today, in addition to automated policies that administrators can configure, we’re enabling end users to encrypt and protect sensitive messages with a default “Do Not Forward” notification, as well as other custom policies. End users can now apply encryption and rights protection from within Outlook with just a few clicks.
Another area where we invest in protecting sensitive information is the ability to protect shared messages.
The Top 10 Email Encryption Platforms
Until recently, you could use Office 365 Message Encryption to send secure email to external recipients, but Office 365 Message Encryption offered a different experience than Information Rights Management (IRM). In the new Office 365 message encryption, we’re expanding the feature to include the best of IRM, with the added benefit that the sender doesn’t have to worry about anything before clicking Send. For example, by removing implicit trust between organizations, we are removing complexity. Users can now easily send encrypted and proprietary messages internally and to anyone.
This not only prevents confidential information from being read by an unwanted audience, but also allows you to set access rights so that the message is not forwarded, copied or published.
Finally, so users can securely collaborate on secure email, Office 365 users can enjoy a seamless reading experience on any device, whether they’re using Outlook (desktop, Mac, web, iOS, or Android mobile) , for users who choose. . To use the Outlook app as IT, we’re adding the ability to enable other Exchange ActiveSync (EAS) mobile email clients, such as the native Messages app on iOS, to receive and reply to protected emails.
Ensure that protected emails can be easily read and replied to by recipients regardless of the device, application, service or identity they use to receive their email.
Everything You Need To Know About Microsoft Office 365
Another investment we’ve made is to allow users to read protected messages regardless of their email provider. Previously, recipients of Office 365 encrypted messages had to use a Microsoft account or a one-time passcode to read an encrypted message.
Today, Gmail and Yahoo allow recipients to easily verify their Google or Yahoo identity and sign in to a specific web browser to read and collaborate on secure emails.
For example, with a Google login page, the recipient can use their Google identity to read a protected message in a specific web view.
Controlled customers have access to customer-managed keys for the Microsoft cloud and the ability to protect their mail using these keys. Exchange Online now supports customer-managed tenant keys for Azure data protection. Read here to understand how to set it up in Azure Key Vault.

The new message protection capabilities are available in Office 365 E3 and above for business customers and Office 365 A1 and above for EDU customers. We offer it in other plans with suitable add-ons. See this table for more details.
Customers should get started with these new capabilities today. Check out the resources below to help you get started:
As we continue to invest in and offer additional data protection capabilities, we’d love to hear your feedback.

Office 365 includes a powerful security feature, Office 365 Message Encryption (OME), which enables organizations to securely send messages across a relatively insecure infrastructure: mail servers. OME combines email encryption with rights management capabilities powered by Azure Data Protection.
Send A Secure Email
Office 365 and Microsoft 365 Suites E3 and E5 plans are licensed for automatic encryption. To use the minimum plan, you must add an additional Azure Data Protection license for each user who requires encryption. If your Office 365 tenant was created after February 2018, email encryption capabilities will be available and enabled automatically. If your tenant was created before that date, Microsoft is slowly but surely picking up the capabilities and making them available to you. They started this process in August 2018, so it shouldn’t be long before your large tenant has access. OME works with Office 365 mailboxes as well as on-premises mailboxes that use Exchange Online protection.
Emails are encrypted using a rights management model. You can use one of the default templates or create your own through the Azure portal.
To send encrypted email using the Outlook client, from the message window, go to the Options tab, click Permissions, and select “Encrypt” from the list of security options.
In Outlook on the web, in a new message window, click Protection on the menu bar, and then click Change Permissions. In the window that appears, select the “Encrypt” protection option.
Microsoft 365 Email Security
When a user sends an encrypted message to an external recipient, the service saves a copy on its own servers and sends a message that looks like this.
When the external user taps the “Read message” button, they can sign in with an existing social account using the email address the message was sent to, or choose to have the service send a one-time access code. to that email address. When any of these conditions are met, the service displays the protected message in a web browser window connected to a page in the Office 365 Message Encryption portal. In addition, the recipient can securely reply to the original sender.
To verify that your tenant is configured for encryption, use the following command, making sure that the sender value is a valid account in your tenant:
When a recipient replies to a protected message, you can configure a rule so that the internal user does not need to log in to the encrypted message portal to view the reply. (Because the response remains on Microsoft’s servers, there is no risk of intercepting the message content in SMTP transit.) To set this rule, use the following command:

The options each user sees depend on the version of Outlook they are using. To access all available encryption options:
Exchange Online Protection (eop) Overview
When choosing a method to encrypt your message, consider the type of permission you want message recipients to have. Regardless of the option selected, the message will be encrypted and recipients will not be able to remove/modify the encryption settings.
If you send an email to a non-Tufts address (for example, Gmail) using the “Tufts – Confidential” or “Tufts – Confidential View Only” encryption settings, the recipient will receive an email informing them that the message is encrypted, but you can’t read it.
If you are using the Outlook for Windows desktop application, you may need to allow your Outlook client to access the Tufts email security templates before using the Encrypt feature. (Note: Even if you never do this, you can still encrypt your emails using the subject line “[Secure]”).
Note: If the recipient sees red or blue X icons in their browser, their email client is blocking images. These images are just the Tufts logo and an encrypted email symbol. They can show or ignore the images which will affect your ability to read the message.
