training on sending encrypted email

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.
