Hi,
I'm making an addIn for outlook which is adding the attachments to the incoming message. I had problems using MailItem.Attachments.Add method so I have used MAPI Ex method to add attachments. I have a problem that attachments larger then 100K are not visible in the message window when the message is stored in folder. There is indicator in explorer window that message contains attachments, and they can be seen and opened(right click on the message, View->Attachments). The code that I'm using is shown bellow. After the outlook is restarted the attachments are visible.Any ideas what I might be doing wrong?

Thanks

Vladimir
