The only redistributable component is MSMAPI32.OCX that implements MapiSession and MapiMessage object. The MAPI compliant email client is required for it to function properly.

>Thanks. I would guess MAPI is like an IEE standard - but it seems different vendors (or software) may have their own MAPI 'package' - or would it be [just] a wrapper to MS's MAPI32 DLL.
