使用EWS API以MSG格式保存电子邮件

问题描述

我正在研究一种解决方案，使用EWS API从交换中提取电子邮件，然后在线上传到SharePoint。下面是文件创建的示例代码，在上传到sharepoint之前。



string mSubject = mItem.Subject;

string targetFileURL = targetFolderUrl +/+ Regex.Replace（mSubject，@[^ \\\\。@ - ]，，RegexOptions.None，TimeSpan.FromSeconds（1.5））;



//将URL限制为150个字符

if（targetFileURL.Length> 150）

targetFileURL = targetFileURL.Substring（0,150）+ .eml;

else

targetFileURL = targetFileURL +" .eml";



mItem。加载（新的PropertySet（ItemSchema.MimeContent））;

MimeContent mc = mItem.MimeContent;

FileCreationInformation newFile = new FileCreationInformation（）;

newFile.Content = mc.Content;

newFile.Url = targetFileURL;

newFile.Overwrite = true;





它非常适合.EML格式，但是当我尝试以.MSG格式保存文件时，它会抛出错误。



有关如何以正确的MSG格式保存文件的任何建议？非常感谢快速回复。



谢谢

Hi,

I am working on a solution to to extract emails from exchange using EWS APIs and then upload to SharePoint online . Below is the sample code for file creation, and before upload to sharepoint.

string mSubject = mItem.Subject;
string targetFileURL = targetFolderUrl + "/" + Regex.Replace(mSubject, @"[^\w\.@-]", "", RegexOptions.None, TimeSpan.FromSeconds(1.5));

//limit URL to 150 characters
if (targetFileURL.Length > 150)
targetFileURL = targetFileURL.Substring(0, 150) +".eml";
else
targetFileURL = targetFileURL + ".eml";

mItem.Load(new PropertySet(ItemSchema.MimeContent));
MimeContent mc = mItem.MimeContent;
FileCreationInformation newFile = new FileCreationInformation();
newFile.Content = mc.Content;
newFile.Url = targetFileURL;
newFile.Overwrite = true;


It works perfectly well for .EML format but when I try to save the file in .MSG format it throws error.

Any suggestions on how to save the file in proper MSG format? Will greatly appreciate quick responses.

Thanks
