An Outlook user had this question: “Can I set the default due date for tasks in Outlook 2007 to "None". Most of the tasks I create (using the To-Do Bar’s Type a Task field) do not require a due date. The default seems to be "Today".”

None is the default for Tasks created using the New button (and can’t be changed). My default using your method is Tomorrow, so yes, you can change it.

The default Due date when you create a task from the To-do bar is the default quick click flag date. You can set the quick click flag to None or use buttons or shortcuts to open task forms. (Open a new task form with Ctrl+Shift+K when in any Outlook folder.)

To change the default Quick Flag, right click on the flag column and choose Set Quick Click from the bottom of the menu.
