  • What is "real source path"? File name and the fully qualified path?

    Outlook simply does not store that information, and an attachment does not have to come from the file system at any point.

  • Hello,

    For the path of attachments, what we could get:

    1) the real source path when we insert an attachment

    To get this, we could handle AttachmentAdd or BeforeAttachmentAdd event.

    2) the path of an temporary file for attachment preview  

    My outlook temporary folder is in


    You could get the path from Registry key OutlookSecureTempFolder under HKEY_CURRENT_USER\Software\Microsoft\Office\X.0\Outlook\Security

    So i dont think we could get the real source path of an attachment in a .msg file attachment.
