Outlook Folder - FolderRemove Event

[Atul Sureka]

Hi

I am using the following code to track FolderRemove event of task Folder and its SubFolders.

using System;

using System.Collections;

using Outlook = Microsoft.Office.Interop.Outlook;

class Temp

{

public static void Main()

{

MyClass obj = new MyClass();

Console.WriteLine("Listening ...............");

Console.ReadLine();

}

}

class MyClass

{

Outlook.Application app;

Outlook.NameSpace nSpace;

// Stores the "Task" Folder

private Outlook.MAPIFolder mapiFolder;

// ArrayList to store the subFolders

private ArrayList subFolderList;

public MyClass()

{

try

{

app = new Microsoft.Office.Interop.Outlook.Application();

nSpace = app.GetNamespace("MAPI");

mapiFolder = nSpace.GetDefaultFolder(Outlook.OlDefaultFolders.olFolderTasks);

subFolderList = new ArrayList();

GetSubFolderList(mapiFolder);

itemsList = new ArrayList();

}

catch (Exception Ex)

{

Console.WriteLine(Ex.Message);

}

}

// Recursive function to attach events with folders and its subfolders

void GetSubFolderList(Outlook.MAPIFolder folder)

{

Outlook.Folders fol = folder.Folders;

subFolderList.Add(fol);

// Attach event handlers

fol.FolderRemove += new Outlook.FoldersEvents_FolderRemoveEventHandler(fol_FolderRemove);

fol.FolderChange += new Outlook.FoldersEvents_FolderChangeEventHandler(fol_FolderChange);

foreach (Outlook.MAPIFolder f in folder.Folders)

{

// Recursivly call for the subfolders

GetSubFolderList(f);

}

}

void fol_FolderChange(Microsoft.Office.Interop.Outlook.MAPIFolder Folder)

{

Console.WriteLine("Folder has been changed....");

}

void fol_FolderRemove()

{

Console.WriteLine("Folder has been removed....");

}

}

Lets My Outlook has four folders with following hierarchy.

Task // Main Task Folder of Outlook

F1 // SubFolder of Task Folder

F2 // SubFolder of Task Folder

F3 // SubFolder of F1

When I delete F1 "FolderRemove" Event is getting fired.

However when I delete F3 "FolderChange" Event is getting fired

Why this is happening ?????

FolderChange fires on the Tasks folder because the subfolder (F1) is
modified - one of its own subfodlers is deleted (F3).

When I delete F3 - it means that I have modified F1, so FolderChange event
of F1 is getting fire - that is fine - But I have also attached handler for
FolderRemove event of F3, So If I delete F3 then FolderRemove event for this
folder should also fire. unfortunately this is not firing ??????

No, FoldderRemove is supposed to fire on the parent folder's
MAPIFolder.Folders collection.
