Returning S_OK from OnReadPattToSzFile() should signal Microsoft Outlook that the extension has handled the task of attaching the file on its own.

Steps To Reproduce

  2. Register the extension and launch the client.
  3. Compose a new message.
  4. Select Insert from the File menu and and select a file.

Results:

The file gets attached to the message.

Expected Results:

The file does not get attached to the message.
