Compare the object variables for the two folders directly (If objA =
objB).
Compare objA against objB returned from the
NameSpace.GetDefaultFolder(olFolderDeletedItems) method.
You could also examine the Name property (there *should* only be one
"Deleted Items" folder in a store), or check the MAPIFolder.FolderPath
property (\\<mailboxname>\Deleted Items would indicate the right folder in
case of duplicates, because it is placed at the root).
