I have a rule to move calendar invites containing some words in the subject to a secondary calendar (a folder in the rule's terms), the problem is that outlook automatically add those invites to my main calendar, so I endup having the event on both my main and my secondary calendar. What can I do to get the calendar events matching that rule to be only on my secondary calendar.

The rule reads like this:

Apply this rule after the message arrives

with 'foo' or 'bar' or 'other words' in the subject or body

and which is a meeting invitation or update

move it to the Secondary-Calendar folder

and stop processing more rules

The calendar sniffer adds it to the default calendar automatically. Your best bet might be to use a run a script rule to delete it from the default calendar or to move the associated appointment to the second calendar.
