Last project I was working on had lot of customisation for Outlook 2003 and its integration with MOSS (Sharepoint 2007). Its altogether a unique experience working with Outlook object model and creating a custom outlook plugin.
Following is a small snippet for adding or manipulating context menu within outlook explorer.
//get outlook explorer object
private Outlook.Explorer actExplorer = this.ApplicationObject.Application.ActiveExplorer();
//get instance of all command bars
private CommandBars cmdBars = actExplorer.CommandBars;
cmdBars.OnUpdate += new _CommandBarsEvents_OnUpdateEventHandler(CommandBars_OnUpdate);
/// <summary>
/// Implements the OnUpdate event for outlook command bars.
/// </summary>
private void CommandBars_OnUpdate()
{
foreach (CommandBar cmdBar in actExplorer.CommandBars)
{
if (cmdBar.Name == "Context Menu")
{
//remove protection
MsoBarProtection oldProtection = cmdBar.Protection;
cmdBar.Protection = 0;
//create custom menu item
CommandBarButton checkInMenuItem = (CommandBarButton)cmdBar.FindControl(MsoControlType.msoControlButton, Type.Missing, "Custom Menu", Type.Missing, Type.Missing);
if(checkInMenuItem == null)
{
checkInMenuItem = (CommandBarButton)cmdBar.Controls.Add(MsoControlType.msoControlButton, Type.Missing, Type.Missing, Type.Missing, true);
checkInMenuItem.Caption = "Custom Menu";
checkInMenuItem.Click += new _CommandBarButtonEvents_ClickEventHandler(checkInMenuItem_Click);
}
//set protection level
cmdBar.Protection = oldProtection;
}
}
}
