    I recently noticed that my Outlook has become very slow, and I suspect it might be due to duplicate PST files stored on my computer. I have multiple PST files with similar names, and I am not sure which ones are actively used by Outlook. Can someone guide me on the best way to identify and clean duplicate PST files safely without losing any important emails? Also, what are some tips to optimize Outlook performance after removing duplicates?
