PostItem.Display Method (Outlook)
Displays a new Inspector object for the item.
The Display method is supported for explorer and inspector windows for the sake of backward compatibility. To activate an explorer or inspector window, use the Activate method.
If you attempt to open an "unsafe" file system object (or "freedoc" file) by using the Microsoft Outlook object model, you receive the E_FAIL return code in the C or C++ programming languages. In Outlook 2000 and earlier, you could open an "unsafe" file system object by using the Display method.
