我的应用程序发送包含几张图片的HTML电子邮件通知。我们使用自定义功能区按钮捕获回复消息。当用户回复时，系统会提示他们通过对话框从互联网上下载内容。如果他们选择＆＃34;否＆＃34;，当我在VSTO中获得该项目时，它有三个或四个.jpg附件。如果他们选择＆＃34;是＆＃34;我没有像预期的那样附上任何附件。
附件命名为＆＃34; ~WRDxxx.jpg＆＃34; xxx通常是＆＃34; 000＆＃34;但偶尔会有其他数字，然后是image001.jpg，image002.jpg等等。文件存在并消耗存储，低于1k（除了~WDD ...约为3.5k），但似乎不包含任何图形。我认为这些是我们的电子邮件提供商嵌入的像素，最大的可能是我们的徽标，尽管附带的文件是空的。
我们使用VSTO和Outlook Redemption混合来访问电子邮件。
这个问题影响了2007-2013，但是内联的默认情况下切换使问题更加紧迫。
