    Hi Angela,

    Welcome to the Microsoft Q&A forum.

    Microsoft provides official documentation on how to send encrypted emails in New Outlook.

    You can refer to the following Microsoft support articles:

    Please note that the Encrypt option may not be available if your Microsoft 365 license or your organization's policies do not support Microsoft Purview Message Encryption or S/MIME.

    If you do not see the Encrypt button in New Outlook, please contact your organization's Microsoft 365 administrator to verify that email encryption has been enabled for your account.

    I hope this information is helpful.

    If you have any questions or need further assistance, please feel free to share them in the comments on this post so I can continue to support you.

    I look forward to continuing the conversation.

    If the answer is helpful, please click "Yes" and kindly upvote it.

    Yes. For New Outlook, the available Microsoft guidance covers both setup and sending encrypted messages:

    • Set up encryption and digital signatures first: Outlook requires setup before sending encrypted mail. This applies to New Outlook, classic Outlook, and Outlook on the web.
    • Send encrypted mail in New Outlook:
      1. Open a new email.
      2. Select Options.
      3. Select Encrypt.
      4. Choose the protection you want, such as Encrypt or Do Not Forward.
      5. Finish the message and select Send.

    Important details for New Outlook:

    • New Outlook supports Microsoft 365 Message Encryption when the email server has an Office 365 Enterprise E3 license.
    • If that is not available, encrypted messages can be sent using S/MIME.
    • S/MIME and Microsoft Purview Message Encryption with IRM should not be combined on the same message. If a message is already signed or encrypted with S/MIME, remove that before applying IRM protection.

    If the goal is training material, these Microsoft articles are the relevant end-user guidance for learning and step-by-step use in New Outlook.
