HRESULT HrGetAutoDiscoverXML( 
    __in_z const WCHAR *pwzAddress, 
    __in_opt_z const WCHAR *pwzPassword, 
    __in_opt HANDLE hCancelEvent, 
    __in_opt ULONG ulFlags, 
    __out IStream** ppXmlStream);

Parameters

  • pwzAddress
    [in] A null-terminated Simple Mail Transfer Protocol (SMTP) e-mail address of the account for which you want to retrieve the auto-discovery information.

  • pwzPassword
    [in] An optional password for the account specified by pwzAddress. Note that passing any password has no effect if the account specified by pwzAddress does not require a password.

  • hCancelEvent
    [in] An unset Win32 event handle that is optional and can be used to cancel the operation. To cancel the operation, set the event and pass the event handle as hCancelEvent; pass null if you do not want to cancel the operation. Note that passing a value that does not represent an event handle has no effect and is ignored by the function.

  • ulFlags
    [in] This parameter is not used. It must be 0.

  • ppXmlStream
