C# script to open email attachment(.msg) in a folder and download attachment. RRS feed

  • Question

  • Hi,

    Could any one suggest any Visual studio C# script to download the attachment from the /msg file in an offline folder (any folder on shared drive).

    I have seen many scripts from the mail server but I need to open .msg which is offline and download the attachment.

  • The following does not handle downloading, only extraction from .msg files. I've used it solely for unit test.

    See MsgReader - there are samples in the first link.

  • There are several methods.

    The simplest one is to use Outlook Interop =>

    Microsoft.Office.Interop.Outlook.Application oOutlookApp = new Microsoft.Office.Interop.Outlook.Application(); 
    MailItem oMailItem = null;
    oMailItem = oOutlookApp.CreateItemFromTemplate("e:\\test.msg");
    Attachments oAttachments = oMailItem.Attachments;
    for (int i = 1; i <= oAttachments.Count; i++)
        Attachment oAttachment = oAttachments[i];
        oAttachment.SaveAsFile(AppDomain.CurrentDomain.BaseDirectory + oAttachment.FileName);
        oAttachment = null;
    oAttachments = null;
    oMailItem = null;
    oOutlookApp = null;
