Your default calendar (and ALL your other default folders are included as
well) is _always_ the calendar in the data store marked as "default" on
Tools?>Account Settings>Data Files.
The gottcha there is "THE calendar in the...". I have more than one
calendar in the default data store. If I use some calendar I've added
or a subfolder calendar it doesn't behave the same as the "main"
calendar. If I create an event and send invites it does track the
responses the way it would if it had been made in the "main" calendar.
If I receive an invite and accept it it goes into my "main" calendar
even if I would rather use another. So if I could just tell outlook
which calendar it should treat as "main" I think I would have it
licked. I use a calendar sharing system that leaves the default
calendar as a personal calendar and makes subcalendars that you share,
and the calendars of others you have permission to see become
subcalendars. So I need to make my shared subcalendar the "main".
Thanks
