I use Office 2007.

I recently published my calendar to Office Online and gave my wife
permission to view the calendar. She can see my calendar in her Outlook but
I notice that she does not receive any updates. When I view my calendar
online, I see the updates are there. Did we miss a setting somewhere to
make sure she gets the updates.

Do I have to publish my calendar each time I make updates? If I do so, do I
have to invite her again to see it?

I understand that the calendar updates are to go to the online published
calendar at each manual or automatic send/receive. But I'm not sure this is
happeneing.
