Reading Outlook 2007 .msg file with VB.Net 2010

[MLarsB]

I am using the following code to get information from Outlook .msg files (created by Save As from
Outlook), such as .SenderName, etc., as shown in the code. This works on all but two of many
.msg files.

The problem is that it does not work on .msg files that are actually saved meeting notices.
I get the following error:
Unable to cast COM object of type 'System.__ComObject' to interface type
'Microsoft.Office.Interop.Outlook.MailItem'. This operation failed because the QueryInterface
call on the COM component for the interface with IID '{00063034-0000-0000-C000-000000000046}' failed
due to the following error: No such interface supported (Exception from HRESULT: 0x80004002
(E_NOINTERFACE))

Then I have to exit Outlook to clear the error.

I have searched with Google and found another person who had this problem, but no solution was given.

Any ideas of how to process the meeting notices?

Thanks.

  Dim oOutL As New Outlook.Application
  Dim oMail As Outlook.MailItem
  Dim email As Outlook.MailItem

      oMail = CType(oOutL.CreateItem(Outlook.OlItemType.olMailItem), Outlook.MailItem)

      Dim MsgFileName As String
      MsgFileName = ChangeToSharedPath(gsDatabaseNames(iThisDatabase))

      email = oMail.Application.Session.OpenSharedItem(MsgFileName)

      With email
        AllOfMSGPreserveCase = .SenderName & .SentOn & .To & .CC & .BCC & .Subject & .Body
        AllOfMSGPreserveCase &= AttachmentsList
      End With
