MapiSendMail on Vista Fails if Outlook 2007 Running?   

I have some code to send mail from an application via MAPI from managed code 
as follows:


    <DllImport("MAPI32.DLL")> _
     Private Shared Function MAPISendMail(ByVal sess As IntPtr, ByVal hwnd 
As IntPtr, ByVal message As MapiMessage, ByVal flg As Integer, ByVal rsv As 
Integer) As Integer
    End Function

m_lastError = MAPISendMail(New IntPtr(0), New IntPtr(0), msg, how, 0)

this code works fine on XpP and works when outlook is closed, but when 
outlook is running i get

"General MAPI failure [2]        "

any ideas?
