Works like a charm and finally my folders are clean. Thank you!
It took me a few minutes to figure out that I needed to access the settings to include special folders (such as sent items) and adjust the criteria. This is, however, entirely my bad. Somehow I had expected it in the context menu, but I agree that this is better accessed through settings.
