The trick is to use CommandBars to execute the New command. See http://www.outlookcode.com/codedetail.aspx?id=616 for a code sample.

In versions before Outlook 2007, Outlook does not directly expose the right-click context menu in its CommandBars collection. You will, however, see a new right-click command is when the item selected is using a custom form that includes one or more custom actions. You can also add a custom action without using a custom form, as demonstrated at http://www.outlookcode.com/codedetail.aspx?id=526

Richard Kagerer has posted a code sample at http://www.outlookcode.com/codedetail.aspx?id=314 that shows how you might trick Outlook into exposing the context menu through Explorer.CommandBars.

Outlook 2007 provides Application-level events for the most commonly used context menus.

I am trying to create an holiday planner, which relies on the
appointment technique. So far I created a button to open the
appointment form with some pre-defined parameters.
But now I have the problem to get the information of the selection in
the calendar. For example: marked from 9.30 to 15.30. Then press the
button to open the form. But how can I get the information of the
selection into the form?


Another question: how can I add "new holiday" to the right-click-menu
on the calendar. the menu bars are no problem, but the context menu
is.
