Is there any way to set the Importance Tag (High Importance, Low Importance,etc.) programmatically in Outlook? RRS feed

  • Question

  • I know how to do this in VBA, but can't find a way to do it in the Office Add-on API.

    (I'm using the Office Developer's tools (JavaScript and HTML)).

    Thank you.

  • Hi,

    Should be something like this: 

    Content-Type: application/json
      "Subject": "Did you see last night's game?",
      "Importance": "Low",
      "Body": {
        "ContentType": "HTML",
        "Content": "They were <b>awesome</b>!"
      "ToRecipients": [
          "EmailAddress": {
            "Address": ""
