Hello guys,
I got a question I can't figure out in outlook '07

I have an event set in the alarm, that has start date jan-02-12 and the end date is july-01-2012.
I want an alarm or reminder to pop 30 days before the end date.
Right now if I put the alarm in any time it seems to be working before the start date, but I wan't to know before it finish.

Anybody knows how to do this?

Thanks in advance.
