I want to be able to use Outlook to record and store a lot of my
life's incidental information that is date related. Sort of like how I
would add notes to a paper diary. If I could actually keep one! I use
Outlook 2007 on a daily basis.

For example while I can add birthdays, etc, as recurring calendar
events I also want to add things like the duration of my holiday,
medical and financial notes, etc. How can I keep all of this
information in one place and make it easy to see on my calendar? Do I
attach it to OneNote? This year I am in a role where I need to share
my calendar with other team members. Do I mark all of this information
as private or do I create two separate calendars?

I would appreciate some ideas from more experienced users than I am.
