How to know if Meeting responses comes from serie or ocurrence/exception?

[frilian]

Hello.

Someone knows how can be identified a mail item to be a complete serie response or an individual ocurrence response from a serie?

I can identify by item class if it's a positive, negative or tentative response, but I don't know how could I check if it refers to the complete serie or to the individual ocurrence.

I'm working with outlook 2007 and with several secondary calendars.

Thanks.
