Can a email be sent as private or confidential

I think that you will have to use Exchange web service.

Brad Orluk has written a blog with an example of using Exchange web service : Polling a users Exchange Online Out Of Office (OOF) status in using Nintex Workflow for Office 365

Here's the method documentation that you should use to create an email : CreateItem operation (email message)

And here's a list of all the properties of an email : https://msdn.microsoft.com/EN-US/library/office/aa494306(v=exchg.150).aspx

You can use the "sensitivity" property which possible values are :

• Normal
• Personal
• Private
• Confidential

Hope this helps

Thank you Caroline Jung​ your code worked perfectly. I attached the workflow file.

Nintex Workflow, use the "Web request" action and configure it like the following to send a private email :

• url : https://your_exchange_server_address/EWS/Exchange.asmx for Exchange OnPremise or https://outlook.office365.com/EWS/Exchange.asmx for Exchange Online
• username/password : enter a username and password of a user who can send email (it will be the sender of the email)
• choose POST
• content type : text/xml; charset="utf-8"
• content of the request (just replace the email address, subject and body) :

<?xml version="1.0" encoding="utf-8"?>

<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"

  xmlns:t="http://schemas.microsoft.com/exchange/services/2006/types">

  <soap:Body>

    <CreateItem
MessageDisposition="SendAndSaveCopy" xmlns="http://schemas.microsoft.com/exchange/services/2006/messages">

      <SavedItemFolderId>

        <t:DistinguishedFolderId
Id="drafts" />

      </SavedItemFolderId>

      <Items>

        <t:Message>

         <t:ItemClass>IPM.Note</t:ItemClass>

         <t:Subject>This is the subject of the email</t:Subject>

         <t:Sensitivity>Private</t:Sensitivity>

         <t:Body BodyType="HTML">This is the body of the email</t:Body>

          <t:ToRecipients>

           <t:Mailbox>

             <t:EmailAddress>email.address@domain.com</t:EmailAddress>

           </t:Mailbox>

          </t:ToRecipients>

          <t:IsRead>false</t:IsRead>

        </t:Message>

      </Items>

    </CreateItem>

  </soap:Body>

</soap:Envelope>
