  • My Microsoft Outlook PST file has become extremely large due to years of emails, attachments, and archived data. Because of its oversized size, Outlook has started running very slowly and sometimes even freezes during search or sending/receiving mail. I want to compress or reduce the size of my PST file, but without losing any important emails or attachments. I tried deleting some old emails, but the file size is still huge.
