I am using Microsoft Outlook on a Windows system, and my PST file has grown very large over time (more than 20 GB). Because of this, Outlook has become slow and sometimes shows performance issues while opening emails and searching data. I want to safely reduce (shrink) the size of my Outlook PST file without losing any emails, contacts, or attachments. Can anyone suggest the best and most reliable way to shrink Outlook PST files on Windows?
