    I am using Microsoft Outlook on my Windows PC, and my PST file has become very large. Because of this, Outlook is running very slowly and sometimes even freezes while opening emails. My PST file size is more than 15 GB, and I want to reduce it safely. I do not want to delete any important emails, contacts, or attachments. I am working on a Windows system and using Outlook from Microsoft. Can anyone please suggest a simple and reliable way to compress Outlook PST files on Windows without data loss?
