Deleted Items

Hey guys, I want to check if an item exists in the DeletedItems Folder,
but if I use item.Parent, it will show me the original folder of the
item. So if I delete a task through outlook UI, and then in my code
check the Parent it will still show as Tasks until I shutdown outlook
and restart. It is like it does not pick up the fact that this item is
in the Deleted Items folder until I restart outlook. I do not want to
enumerate through all of the deleted items each time, so do you have any
suggestions?
Thanks

Please show the code you're using the access the item and explain what event you're using to run it.

Thanks as always Sue:

Outlook.MAPIFolder mFolder
=(Outlook.MAPIFolder)HelperClass.GetPropertyHelper(item, "Parent");
string fname = mFolder.Name;

if(fname.IndexOf("Deleted") >= 0)
{

}

"fname" seems to be the original folder that the item was deleted from,
not the deleted items folder. If I close outlook and restart then it
picks up.
I am running this code on a button click not on any outlook event.

How does GetPropertyHelper work? And how -- and when -- is Item instantiated?

public static object GetPropertyHelper(object targetObject, string
propertyName)
{
try
{
return targetObject.GetType().InvokeMember(propertyName,
System.Reflection.BindingFlags.Public |
System.Reflection.BindingFlags.Instance |
System.Reflection.BindingFlags.GetProperty,
null,
targetObject,
null,
System.Globalization.CultureInfo.CurrentCulture);
}
catch(System.Exception ex)
{
GlobalConstants.Log(log, "Error", "GetPropertyHelper", ex);
return null;
}
}

and
object item =
this.OutlookApp.GetNamespace("MAPI").GetItemFromID(entryID, storeID);

Thanks so much.

I even tried using redemption and getting property 0x0E090102 but it
returns the entryid of the contacts folder (where it was deleted from)
not the entryid of the deleted items folder. but if I use OutlookSpy and
look at 0x0E090102 property then it shows the entryid of the Deleted
Items folder for that Contact.

Have you released all references to the original object and since you're
using .NET code also called Marshal.ReleaseCOMObject and called the garbage
collector? Outlook caches items and their properties and the fact that
things work if you close and restart Outlook makes it look like it's a
caching problem. As long as an item is cached it will return its original
properties back.

Thanks Ken for your help on this.
Only problem is I do not maintain a reference to this contact until I am
trying to find it when the button is clicked:
I use this code to get the object:
object item =
this.OutlookApp.GetNamespace("MAPI").GetItemFromID(entryID, storeID);
but I do not maintain a reference to item outside of this function call.

If I get the item as above and then call:
System.Runtime.InteropServices.Marshal.ReleaseComObject(item);
GC.Collect();
GC.WaitForPendingFinalizers();

it does not seem to do anything about releasing the cache.
Any ideas?
Thanks so much as always

Well, I'm sorry to tell you nothing really looks wrong in your code

The only thing I can think of and it's a stretch, is that you might try
getting each component object as a separate object instead of using dot
operators, where Outlook always creates internal variables. So for example
set a NameSpace object and use that to call the GetItemFromID method. Also
see if you are doing anything further on in that code that might call a
procedure or item method that somehow might also be creating an implicit
object variable that isn't being released when expected.

I'd also be curious to see if you put up some button or something and waited
a while, like 5 minutes, before clicking it and seeing if the GetItemFromID
code worked then. Just for testing of course.

Yes it seems if I do wait some period of time after deleting an item
from the contacts folder it will be picked up that it has moved into the
Deleted Items Folder.
What is odd too is, I used OutlookSpy to look at PR_PARENT_ENTRYID and
it shows the deleted items folder enntry, but if I use the same in my code:
safeMailitem.get_Fields(235471106); it will return the entryid of the
Contacts folder.
