.... but too much variety will make it difficult for users to fill out the form efficiently.
Let's start with Yes/No choices. Those are best handled with a check box. And they're easy to create. Just drag your custom Yes/No field from the Field Chooser to the form page and Outlook will automatically create a check box.
Where you have 3-5 choices, either option buttons, a combo box or a list box would be the most appropriate. Option buttons are the trickiest to set up, but are probably the most intuitive for users, because they clearly show that the choices are mutually exclusive. On an Outlook form, if you have more than one button set, put each in a frame. THen, for each button in a set, bind it to the same Outlook property on the Value tab of the button's Properties dialog and set the value that you want that Outlook property to store when the user clicks that button.
