Yes, I know. For those events that have reminders (and it's curious that
your public holidays do, because mine don't) that you don't wish to see then
just open the holiday appointment (open the series, not the individual
occurrence) and turn off the Reminder. Yours are set to Show Time As "Free"
right?
Unfortunately, the holidays Outlook adds with the Add Holidyas function are
not recurring event, but a series of six or so individual entries for each
event. What I'd do for this case would be to use the By Category view, then
add the Reminders column and group by that as well. I could then select all
the "Reminders: Yes" entries and drag the selection to the "Reminders: No"
group to remove the reminders.
