ID: Q234539

The information in this article applies to:

SYMPTOMS

Returning S_OK or S_FALSE from IExchExtAttachedFileEvents::OnReadPattFromSzFile() in a client extension has the same effect. In either case, Microsoft Outlook will continue to call extensions and complete the work itself.

STATUS

MORE INFORMATION

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

Write an extension that returns S_OK to OnReadPattToSzFile(), where the extension does nothing to attach the attachment.

Compose a new message.

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.
