I am facing a serious issue with Microsoft Outlook due to an oversized PST file. Over time, my mailbox has grown very large, and now Outlook is running slowly, freezing frequently, and sometimes failing to open at all. I have already tried deleting emails and emptying the Deleted Items folder, but the PST file size does not reduce significantly. I am worried about data loss and want a safe and reliable way to shrink or compact my oversized PST file without damaging emails, attachments, or folder structure. Is there an effective solution to reduce PST file size while keeping all data intact?
