I am facing an issue where my Outlook PST file has grown beyond 50GB, and now Outlook is starting to lag and sometimes fails to open properly. I have already tried archiving old emails, but the file size has not reduced much. Can anyone suggest a reliable way to compress or reduce the size of an oversized PST file without losing any data? Is there any manual method or tool that can help with this issue?
