As many users have discovered, Options, Calendar Options, Add Holidays only adds the holidays to the default Microsoft Outlook calendar. Many users wonder how they'll get the Holidays on the other calendar.
It's easy - add the holidays to the default calendar then move or copy them to the other calendar.
- Switch to the By Category view. The View selector is on the Advanced toolbar or look for it on the View menu.
- Select the Category
- Drag it to the second calendar folder. Left click drag will move the holidays, right click and drag will give you the choice of Move or Copy.
If you aren't good at dragging, you can select the Holidays and use the Edit, Move to Folder or Copy to Folder Command.
