Are we assuming a form in design mode?
Note sure the context of your question, since there are a “lot” of places where you can display properties for a given object.
The property sheet for a form can only show in layout view, and in design view.
Previous versions of Access (2000-2003) did allow display of the property sheet in form view, but since 2007, you can only display the property sheet in layout view, and in design view.
So do expand more on the “context” of your question – it not clear when and where you are attempting to display the property sheet, and it not clear what kind of object (form, report etc.) you are attempting to display the property sheet for.
So later versions of Access don’t display the property sheet in form view anymore.
