尝试发送邮件时出错.不使用EWS发送 [英] Error trying to send mail. Not sending using EWS

问题描述

我可以很好地连接到Exchange Server，并且可以收到所有未读邮件，但是新邮件不想发送

I'm connecting fine to the Exchange Server and I'm getting all the unread mails but a new message doesn't want to send

消息代码

var newHTML = html.HTMLCode.Replace("{House}", house.Number)
                           .Replace("{Token}", token.Number)
                           .Replace("{contactPerson}", 
                                    string.Format("<a href=mailto:{0}>{1}</a>", 
                                    contactPerson, contactPerson));
LogError.WriteToFile("Has House and token");
//Send mail with token to user 
EmailMessage message = new EmailMessage(emailService);
message.ToRecipients.Add(email.From.Address);
message.Subject = string.Format("Electricity token for: {0}", house.Number);
message.Body = new MessageBody(html.HTMLCode);
LogError.WriteToFile("Trying to send");
message.Send();

我尝试解决此问题，因此在日志文件中显示正在尝试发送"，但发生错误，显示为 请求中必须包含EmailAddress或ItemId."

I have a try catch around this so in the log file I get "Trying to send" but then a error occurs that reads as "EmailAddress or ItemId must be included in the request."

从所看到的示例中，我构造消息的方式似乎足够，但显然不是

From examples seen, the way I construct my message seems sufficient but clearly isn't

推荐答案

这是我收到所有未读电子邮件的方式

This is how I got all my unread emails

 SearchFilter sf = new SearchFilter.SearchFilterCollection(LogicalOperator.And, new SearchFilter.IsEqualTo(EmailMessageSchema.IsRead, false));
            ItemView view = new ItemView(int.MaxValue);
            FindItemsResults<Item> findResults = emailService.FindItems(WellKnownFolderName.Inbox, sf, view);
            foreach (EmailMessage email in findResults)
            {}

请注意，我将它们作为"EmailMessage"获得

Note that I got them as a "EmailMessage"

但是由于无法获得发件人的电子邮件地址，所以这就是它不想发送的原因. 然后我找到了这篇文章: FindItem仅返回任何可流属性的前512个字节

But were never able to get the senders email address so that's why it didn't want to send. and then I found this article: FindItem returns only the first 512 bytes of any streamable property

因此，我去了接收这样的特定电子邮件.请注意，我现在从findResults获取项目"，并使用该项目"执行以下操作.

So then I went to go get that specific email like this. Note that I now get the "Item" from the findResults and with that "Item" I do the following.

SearchFilter sf = new SearchFilter.SearchFilterCollection(LogicalOperator.And, new SearchFilter.IsEqualTo(EmailMessageSchema.IsRead, false));
            ItemView view = new ItemView(int.MaxValue);
            FindItemsResults<Item> findResults = emailService.FindItems(WellKnownFolderName.Inbox, sf, view);
            foreach (Item item in findResults)
            {
//Get the email message
                    EmailMessage email = EmailMessage.Bind(emailService, item.Id,
                    new PropertySet(BasePropertySet.FirstClassProperties, ItemSchema.Attachments));

                    if (email != null)
                    {}
}

现在我终于可以发送电子邮件了

Now I could finally send emails
