当我尝试通过EWS发送带有内嵌图像(附件)的HTML消息时,这个问题就暴露出来了.但是我退回到最简单的形式,发现我甚至无法发送HTML消息.
我使用的是C#,.NET 4,EWS API 1.1,Exchange Server 2010 SP1.
这是我的代码的核心:
ExchangeConnection = new ExchangeService(ExchangeVersion.Exchange2010_SP1);
ExchangeConnection.Credentials = new WebCredentials(Username, Password, Domain);
ExchangeConnection.Url = new Uri(ServiceURI);
string MailBody = @"<html><head></head><body>
This is a <b>test</b> <strong>HTML</strong> <em>message</em>.<br><br>
Did it work?</body></html>";
NewMessage = new EmailMessage(ExchangeConnection);
NewMessage.Subject = "Test HTML Message #001";
NewMessage.Body = MailBody;
NewMessage.Body.BodyType = BodyType.HTML;
NewMessage.ToRecipients.Add("tony@zierniemann.com");
NewMessage.Send();
使用该代码,我收到一条消息,内容如下:

This is a test HTML message.
Did it work?
没有MIME声明,也没有text/html部分.
如果我通过Outlook(在同一个Exchange服务器上)发送类似的消息,我会得到这样的信息:

This is an HTML message.
What do the headers look like?

任何人都可以向我解释如何使用EWS通过代码获取第二个消息？谢谢!
我刚刚遇到了一个非常相似的问题。我们最终将其确定为一个特定帐户，该帐户收到的是电子邮件的损坏版本，而不是正确的多部分 MIME 文本和 HTML。事实证明，问题在于该帐户在 Exchange 中设置为对 MAPI 富文本电子邮件（在“常规”选项卡中）使用“使用默认设置”，而其他帐户设置为“从不”。
因此，问题基本上是 Exchange 知道要发送到的联系人电子邮件，并尝试“智能”并以 Outlook 专有格式发送它，但该地址的客户端没有使用 Outlook，因此他们无法正确查看电子邮件。我认为也可以在全局级别而不是用户更改此设置，但我不确定它在哪里。
通过 Outlook 发送时它起作用的原因是 Outlook 2010 能够以强制邮件采用 HTML 格式的方式发送电子邮件，而 EWS 托管 API 似乎无法做到这一点。
