exchange server - Save mail to msg file using EWS API

Question

I'm using Exchange Web Services Managed API 1.1 to connect to Exchange server 2010 and then find out new emails received. Now I want to save a copy of the .msg file to a folder on the disk.

I do not want to use any paid third party to integrate.

Any help will be appreciated.

If you are happy to save into the .eml format instead, it can be done very easily just using EWS and no third party libraries. The .eml file will contain all the same information and can be opened by Outlook in the same way as .msg (and also by other programs).

message.Load(new PropertySet(ItemSchema.MimeContent));

MimeContent mc = message.MimeContent;
FileStream fs = new FileStream("c:est.eml", FileMode.Create);

fs.Write(mc.Content, 0, mc.Content.Length);
fs.Close();

Cleaned up code:

message.Load(new PropertySet(ItemSchema.MimeContent));
var mimeContent = message.MimeContent;

using (var fileStream = new FileStream(@"C:Test.eml", FileMode.Create))
{
    fileStream.Write(mimeContent.Content, 0, mimeContent.Content.Length);
}
