These are most likely a symptom of a glitch, corruption, or conflict, and not permanently broken functionality. Start with something simple, like Safe Mode or resetting the view when your Outlook cleanup not working. For more critical problems, the best solution is to repair your data file or create a new profile. But these also work in limited cases.
