我正在使用Outlook的Office加载项.需要打开带有预定义附件的新邮件.

Then I'm trying to attach this file to a new message in Outlook via add-in outlook API, here is an example from Office Developer that I use to attach the file I just get from the other email (like 'forward' functionality):

  Office.context.mailbox.displayNewMessageForm(
  {
    toRecipients: Office.context.mailbox.item.to, // Copy the To line from current item
    ccRecipients: ['[e-mail]'],
    subject: 'Outlook add-ins are cool!',
    htmlBody: 'Hello <b>World</b>!<br/><img src="cid:image.png"></i>',
    attachments: [
      {
        type: 'file',
        name: 'image.png',
        url: 'http://contoso.com/image.png',
        isInline: true

According to documentation on displayNewMessageForm there are currently two attachment types are supported. To attach file to the item the attachment object should looks like ...

{
    type: 'file',
    name: 'image.png',
    url: 'http://contoso.com/image.png',

{
    type: 'item',
    name: 'image.png',
    itemId: 'ews_item_id_goes_here'
}
