Hi,

I'm using VS2008 & Outlook 2007. My application tries to watch Outlook
folders, their additions, renames, moves and deletions.

I have a wrapper class for a folder that has class level variables for
folder (Outlook.Folder) and it's subfolders (Outlook.Folders). When this
class is initialized, these variables are set and events attached (see below
my code). In ThisAddin_Startup "watched" folder and it's subfolders are
iterated, wrapper classes created and added to a class level hashtable.

The problem is, BeforeFolderMove for a folder in my wrapper class fires only
occasionally, but folder addition and change always do. This shouldn't be a
scope issue, as the two other events do fire. Or what's happening?

Thanks for any help.

....
private Outlook.Folders _folders;
private Outlook.Folder _folder;

public DFolder(Outlook.MAPIFolder folder)
{
// Set folder variables
_folder = folder as Outlook.Folder;
_folders = folder.Folders;

// Setup events
_folder.BeforeFolderMove += new
Outlook.MAPIFolderEvents_12_BeforeFolderMoveEventH andler(folder_BeforeFolderMove);
_folders.FolderChange += new
Outlook.FoldersEvents_FolderChangeEventHandler(fol der_FolderChange);
_folders.FolderAdd += new
Outlook.FoldersEvents_FolderAddEventHandler(folder _FolderAdd);
}

_folder and _folders variables must be declared on the class level. In your
case they are local variables; as soon as the GC releases them, no events
will be fired.

Hi Dmitry,

those variables are on the class level and FolderChange and FolderAdd events
do always fire. The problem is only with the BeforeFolderMove event, that
might or might not fire.

Oops, sorry, I don't know where I was looking :-)
I have heard of problems with BeforeFolderMove (which I personally do not
use) - BeforeFolderMove, unlike FolderChange and FolderAdd events, is a pure
UI event and has no MAPI counterpart. I bet not all codepaths in Outlook
call that event.

_folders.FolderAdd += new

}

Maybe it has something to do with Outlook's internal GC? If I setup a
"watched" folder with BeforeFolderMove event and cancel parameter set to
true, and then trying hit the delete, a few times the event is fired and the
folder is not removed. However, after a while (after GC?) the folder will be
removed because BeforeFolderMove didn't fire.

Fortunately I can use Redemption events for what I need

Thanks!

Hard to say.. Are o usur your obejcts do not get released?
Keep in mind that Redemption won't help you with BeforeFolderMove -
Redemption wraps MAPI events, which firte asynchonously after the action
takes place. BeforeFolderMove is fired by Outlook *before* the folder is
deleted.
