If you are using Outlook 2007 you can use the PropertyAccessor object to get
at the Internet email headers. If you're using an earlier version that's not
exposed in the Outlook object model. For earlier versions you have to use a
different API such as CDO 1.21 or Extended MAPI or a 3rd party library such
as Redemption (www.dimastr.com/redemption).

The property tag to use to get the Internet headers is
PR_TRANSPORT_MESSAGE_HEADERS (0x007D001E). The property is a PT_STRING8
property.

Thanks for ur answer. i will try to use Extended MAPI, but i m receiving mail
using outlook object model, will extended mapi or CDO work? bcos i think that
mail will be removed from server n move to inbox of outlook, or CDO ExMAPI
will read mail from inbox rather than server ?

Both CDO 1.21 and Extended MAPI can access items in the Inbox.

hi,i m using this code but code fails at query interface line "error message
is " unresolved external symbol"
error LNK2001: unresolved external symbol _IID_IMAPISession, the line of
code is
CComPtr<IUnknown> punk;
spMailItem->get_MAPIOBJECT(&punk);
punk->QueryInterface(IID_IMAPISession, (void**)&m_pSession);//error line
tell me what to use, or what dll to include, i m confused bcos of not
knowing what dll or lib to use, as i mentioned in previous question.

It depends on whether or not Outlook is installed and set as the mail
provider. In general Extended MAPI will be there and used if that's the
case. Simple MAPI is used by Outlook Express among other applications and is
always used when a Send To, Mail Recipient command is used.

The other way to install Extended MAPI (the MS version) on a computer is to
install the Exchange admin tools, but that's server side MAPI and not client
side MAPI.
