After installed Office 2007 Service Pack 2, if a user attempts to open a Sharepoint item in Outlook, the user may get a dialog to send data to Microsoft.  This pop-up indicates that Duet has failed to work with the item, and we allow the user to send us the data associated with the error.  We have fixed this behavior in KB 978633.  This KB is a hotfix for the Duet client to properly handle the Sharepoint Items, or SharingItems , like a document change notification email.
