I think Ghiadoc was asking what I wanted to ask and Milly has answered it.
In Outlook 2007, I wanted to be able to update the birthday of a contact and
then have that automatically be placed within my Outlook 2007 Calendar.
Well, it does update automatically. I don't know if that is new for the 2007
Beta or has always been there. To do it, go to 'Details' on the page that
shows your chosen contact's information, update the birthday date, save and
'presto!', when you go to that date in your Calendar, there is the recurring
event. If you then double-click on the event in your Calendar, you can set
the reminder period. I don't think you can do this bit from the Contact
page, only from within the Calendar.
