取消Outlook 2010中在日历里添加的假日

在Outlook 2010中可以在日历很容易的添加某个或多个国家的假日。选择File - Option - Calendar - Add Holidays，然后勾选需要添加的国家就完成了。可是当你只添加了一个国家的假日，如德国，过一段时间后想取消这个国家的假日，却不能取消选中的国家，然后点击OK，因为当没有选中任何国家时，只能点击Cancel，而OK变成了阴影无法点击。执行下列操作可以删除日历中的所有假日：

1. In Outlook 2010, in Calendar view, click the "Search Calendar" box. From the Search tab, click Search Tools, and then Advanced Find... .
2. Click the Advanced tab.
3. Click Field, select Frequently-used fields, and then choose Categories.
4. Under "Condition:", use the drop-down list to select contains.
5. Under "Value:", type holiday .
6. Click Add to list.
7. Click Find Now.
8. Maximize the search results window for easy viewing. If you see the message "There are no items to show in this view.", you have no holidays on your calendar.
9. In Outlook 2010, to manually select all of the holidays, click in the results area and press Ctrl-A.
10. In Outlook 2010, right-click the highlighted holidays and choose Delete.

个人认为这是Outlook日历功能设计上的一个缺陷。在下一个版本中会被修正吗？
