I have disabled 'Allow Edit' on both the group and item settings yet it is still possible to create groups and items at runtime. As this offers no benefits to the user I would prefer to disable these features. How exactly is this done?Thanks!
You can handle ContextMenuInitializing (or NavigationContextMenuInitializing for the OutlookNavigationPane style), and cancel the event to prevent the context menu from appearing. The event args class also exposes the ContextMenu as a property so you can add/remove items.
