Outlook.Results.GetNext throws 'The object does not support this method.' - vba

Question

I am running a search in certain folders and their subfolders to move all items in a common parent folder.
When the search is done I get an Outlook.Results item rsts and then want to move all items in the search result. I am at the step where I loop all items, but the last item throws a 440 at the GetNext Method. How can I solve this?

Dim Scope As String
Dim Filter As String

Set sch = Application.AdvancedSearch(Scope, Filter, True)
