About time! Google Calendar is still missing some key functionality: syncing with Outlook and the ability for me to get notifications from all of my calendars. They have this excellent feature where you can get a daily email with a list of your appointments/events for that day. However, it will only mention those from your “primary” calendar. This turns what could be a very nice marketing feature into a needlessly hobbled waste of time.
One day perhaps Google will offer a free Outlook Exchange type service for mail, contacts and calendar. I can dream, right?
