I am facing an issue with my Outlook PST file as it has grown very large and is slowing down Outlook. I want to reduce the PST file size by removing old or unnecessary emails, attachments, and other data, so that I can free up storage space and improve Outlook performance. Can anyone guide me on the best methods or tools to safely remove old emails, archive data, or compress the PST file without losing important information?
