How do I add holidays to a 2007 Outlook calendar?
Open Outlook 2007 and select “Options” from the “Tools” menu. Click “Calendar Options” and then click “Add Holidays.” A box pops up with a list of countries and regions. Place a check mark in the blank box to the left of the country name for each country whose holidays you want to add to your Outlook calendar, then click “OK.” (Your own country or region is automatically selected.) Close Outlook and then reopen the program.
