Graph API and Email Sending - Way to enable "encrypt" option?

Question

We use an API interface that interfaces with the Graph API to handle sending messages for a specific automated service. We don't currently specify "Encrypt" as the rights management state/template to use for sending the email out, but we do have a flow rule that forces Encryption when that email address sends.

Is there a specific flag or such that we can pass to the mail sending API components of the Graph API to select the "Encrypt" rights protection option, or is that not even an option in the API calls for sending a message?

Hi Thomas Ward

Thanks for reaching out.

There is nothing explicit in the Graph for doing encrypted emails.

However, the Graph allows you to send native MIME email https://learn.microsoft.com/en-us/graph/outlook-send-mime-message so this allows you to use SMIME for encryption and signatures.

or would you consider filing a feature request on the M365 developer platform so this can be looked into?
