Could anybody give me a clue as to how to gain access to .msg files
using MAPI?

I have written an app that the attachment of every email in a mailbox
to a file on disk. These .msg files also contain attachments, how can
I access these?

Alternatively, how could I go about saving these .msg attachments to
another mailbox?

I've got the code in C# if you need it.

Many thanks.

use IConverterSession interface!!!

well I have also developed a similar application!!! Are you coding 
completely in C#? or using VC++ ??

Do you mean standalone MSG files or embedded message attachments?

Thanks for the responses.

I'm coding entirely in C# for this, I'll look into the
IConverterSession interface but would appreciate any hints/tips.

I'm working with standalong .msg files.

Also, I noticed an application called msgDetach which performs the
required task but I'd prefer not to resort to foreign code in my
solution.

Thanks

IConverterSession  has nothign to do with MSG files, it is used to convert 
to/from MIME format.
What *exactly* are you trying to do with the MSG files?

Use something like [this may not be the best way to. Use it at your own risk]


#define _MSGSESS IMessage
#include <imessage.h>
.
.
.then
 	CComPtr<IMessage> pMessage;
	CComPtr<IStorage> pStorage;
    	LPMSGSESS  pMsgSession =  NULL;
    	LPMSGSESS  pIMsg = NULL;
	HRESULT hRes;
	LPMALLOC pMalloc = MAPIGetDefaultMalloc();
	hRes = ::StgOpenStorage(L"c:\\a.msg",NULL, STGM_READWRITE | STGM_TRANSACTED,NULL,NULL,&pStorage);
	// Open an IMessage interface on an IStorage object
	if(FAILED(hRes) )
		return;
	//TODO: verify that CLSID is CLSID_MailMessage using ReadClassStg

	// Open an IMessage session.
    	hRes = ::OpenIMsgSession(pMalloc, 0, &pMsgSession);
	if(FAILED(hRes) || !pMsgSession)
	{
		Debug(DebugLevel::Error,_T("Error [%#08x] from OpenIMsgSession - %s"),hRes, CMAPIHealper::GetErrorDetails(hRes));
		return ;
	}

    	hRes = ::OpenIMsgOnIStg(pMsgSession, MAPIAllocateBuffer, MAPIAllocateMore, MAPIFreeBuffer, pMalloc, NULL, pStorage, NULL, 0, 0, &pIMsg);
	if(FAILED(hRes) || !pIMsg)
	{
		Debug(DebugLevel::Error,_T("Error [%#08x] from OpenIMsgSession - %s"),hRes, CMAPIHealper::GetErrorDetails(hRes));
		pMsgSession->Release();
		return ;
	}
	CMAPIHealper::DumpProperties(pIMsg);
	//release other interfaces...

-> at this point you have a valid IMessage interface pIMsg, you can retrieve any properties...

I just ran this code and I could see all the properties correctly. Now that you have an IMessage, you can read its content, its attachment in the usual MAPI way.

Hope you can convert this to C#!

absolutely true!!! I posted that thinking it of MIME format!!

Alternatively, if the .msg file is an embedded message (as an attachment 
in a mail), then you need to do these
-Open the .msg file/attachment using IMessage::OpenAttach, here IMessage 
will be of the message containing the .msg file
-Then call IAttach::OpenProperty requesting an IID_IMessage interface
-Now you again have a IMessage, which is of the embedded message, you 
can do anything you do on a normal message.

Thanks for that, the only reason I'm working with standalone .msg
files is because that was the only way MAPI was allowing to to extract
them. They were originally attached to other emails.

I will see how far I get with IMessage.

I've had little luck with this so far, I was hoping to find some C#
examples of this interface being used but have been unable to. I have
little experience of working with interfaces so don't think I'll be
able to muddle through this until I do, is there any resources you
could recommend for reading up on this?

What exactly you are trying to do??
I guess you already have the code in C# to read open the message and its 
attachment!! So, if you tell us where you are stuck, maybe we can help.

If you are using functions like StgOpenStorage, OpenIMsgSession, 
OpenIMsgOnIStg, you can use P/Invoke

I'm using the Microsoft.Office.Interop.Outlook library to end up with
an Outlook.Attachment from a message. The only function I can find to
do this is Attachment.SaveAsFile. As I am working with a message
attached to a message this saves the .msg file to disk. I would like
to be able to create a Outlook._MailItem from the .msg file in order
to extract the attachment from that.

Here is the source code I am using to extract the .msg files.
'emailbox' is the source inbox and 'output' is the directory where
the .msg files will be stored.

    private static void EnumerateInbox(string emailbox, string output)
        {
            Outlook._Application oApp = new Outlook.Application();
            Outlook.NameSpace oNS = oApp.GetNamespace("MAPI");

            try { oNS.Logon(null, null, false, false); }
            catch (Exception ex)
{ Console.WriteLine(ex.Message); }

            Outlook.Recipient oRecipient =
oNS.CreateRecipient(emailbox);
            Outlook.MAPIFolder folder =
oNS.GetSharedDefaultFolder(oRecipient,
Outlook.OlDefaultFolders.olFolderInbox);
            Outlook.Items items = folder.Items;

            for (int i = items.Count; i >= 1; i--)
            {
                try
                {
                    Outlook._MailItem mailitem =
(Outlook._MailItem)items[i];
                    Outlook.Attachments atts =
(Outlook.Attachments)mailitem.Attachments;
                    Outlook.Attachment att =
(Outlook.Attachment)atts[1];

                    att.SaveAsFile(output +
mailitem.CreationTime.ToFileTimeUtc() + " " + att.FileName);

                    mailitem.UnRead = false;
                    mailitem = null;
                    atts = null;
                    att = null;
                }
                catch (Exception ex) {Console.WriteLine("Error
extracting item " + i + ": " + ex.Message); }
            }
        }

If you are using OOM, the only way to import MSG file is to call 
Application.CreateItemFromTemplate.
<plug>
Redemption (url below) supports both opening the standalone MSG files (see 
RDOSession.GetMessageFromMsgFIle) and importing the contents of any MSG file 
using RDOMail.Import.

That's great, thank you. Redemption made it very easy.

Hi,
I am using RDOSession.GetMessageFromMsgFIle to get RDOMail. I am having 2 
attachments in this Mail. Once I get the names of the attachments, I am not 
able to use the attachments again. I am getting exception "Error in 
IMessage.OpenAttach: MAPI_E_NO_ACCESS". Can anybody please help me.

Thanks,
Zaheer

Messages created MSG files created on top of MSG files won't let you reopen
