I have Outlook 2007. Can I download public holidays etc into my calendar so I
know when bank holidays and mothering sunday happens?
Outlook comes with a predefined list of holidays for specific regionalities
(Tools>Options>Calendar Options>Add Holidays), but you can always add more.
As for most things with Outlook, there are multiple ways to add more. One is
to create your own holiday file and add it. Another is to simply enter them
manually into the calendar and assign to them the Holiday category (or not, if
you don't want the category).
