I've essentially got the same problem. I'm using OL2003 and none of my
contact's birthday / anniversary info is on the calendar. It used to be on
my calendar, but I had to clear out my calendar since pda synching in some
circumstance resulted in duplicates. Now I wish to re-import all of my
contact date-info back into the calendar but can't find a way.
Like 'dantab', my contacts folder is an outlook e-mail address book. But
OL2003 does not appear to have Tools->Options->Preferences->Contact option
for "Contact linking."
