In Outlook Object Model, there are 3 panes in 

Application.ActiveExplorer.Panes. They are Outlook Bar, FolderList and 

Preview.



I would like to add a new pane to show all the e-mail addresses of the 

currently selected item in Inbox. When the user click a custom button on a 

Toolbar, the pane will be shown. The effect is just like clicking on 

the "Organize" button. A portion of the screen will show the "Organize" 

pane, and the FolderList and Preview panes will become smaller.



I have done some research on the Panes object in the Outlook Object Model, 

however, I dont know whether this can be done. Does anyone know that? Any 

commment or advice are high appreciated, Thanks a lot in advance.
