Question

我在服务器上运行作为预定作业的服务。它在一个没有自己邮箱的服务帐户下运行。我们希望它能够从团队的共享收件箱中发送电子邮件在这里使用模仿是我尝试过的。

var service = new ExchangeService
{
    TraceEnabled = true,
    ImpersonatedUserId = new ImpersonatedUserId(ConnectingIdType.SmtpAddress, Resources.EmailUsername)
};

service.AutodiscoverUrl(Resources.EmailUsername, RedirectionUrlValidationCallback);

var email = new EmailMessage(service);

if (!string.IsNullOrWhiteSpace(recipients))
{
    foreach (var recipient in recipients.Split(','))
    {
        email.ToRecipients.Add(recipient.Trim());
    }
}

email.Subject = subject;
email.Body = new MessageBody(BodyType.HTML, body);

if (attachmentName != null && attachment != null)
{
    email.Attachments.AddFileAttachment(attachmentName, attachment);                        
}

email.Send();

它失败了，我得到一个例外说：

当您将请求作为没有邮箱的帐户发出时，您就是必须为任何区分指定邮箱主smtp地址文件夹ID。

TraceEnabled部分让我注意到xml中设置了MessageDisposition=SaveOnly。我查了MessageDisposition，发现我想要SendOnly。

经过多次搜索，我最终来到这里：https://github.com/OfficeDev/ews-managed-api/blob/master/Core/ServiceObjects/Items/EmailMessage.cs
显示：

public void Send()
{
    this.InternalSend(null, MessageDisposition.SendOnly);
}

那看起来就像我想要的那样......但是那时候：

private void InternalSend(FolderId parentFolderId, MessageDisposition messageDisposition)
{
    this.ThrowIfThisIsAttachment();

    if (this.IsNew)
    {
        if ((this.Attachments.Count == 0) || (messageDisposition == MessageDisposition.SaveOnly))
        {
            this.InternalCreate(
                parentFolderId,
                messageDisposition,
                null);
        }
        else
        {
            // If the message has attachments, save as a draft (and add attachments) before sending.
            this.InternalCreate(
                null,                           // null means use the Drafts folder in the mailbox of the authenticated user.
                MessageDisposition.SaveOnly,
                null);

            this.Service.SendItem(this, parentFolderId);
        }
    }
    ...

这两条评论是最具启发性的部分。附件将保存到运行该过程的用户的草稿文件夹中为了解决这个问题，我们在调用Send时必须已经保存了该消息。让我们确保它保存在我们知道的邮箱中。因此，我们删除模拟，添加保存步骤，然后修改“发件人”字段。然后我们可以安全地发送消息，它将自己从草稿文件夹中删除。

var service = new ExchangeService
{
    TraceEnabled = true
};

service.AutodiscoverUrl(Resources.EmailUsername, RedirectionUrlValidationCallback);

var email = new EmailMessage(service);

if (!string.IsNullOrWhiteSpace(recipients))
{
    foreach (var recipient in recipients.Split(','))
    {
        email.ToRecipients.Add(recipient.Trim());
    }
}

email.Subject = subject;
email.Body = new MessageBody(BodyType.HTML, body);

if (attachmentName != null && attachment != null)
{
    email.Attachments.AddFileAttachment(attachmentName, attachment);                        
}

var folderId = new FolderId(WellKnownFolderName.SentItems, Resources.EmailUsername);

email.Save(folderId);
email.From = Resources.EmailUsername;
email.Send();

如果您模仿并且没有邮箱，如何发送带附件的电子邮件
