I urgently need some guidance. I manage multiple Outlook PST files for my office team, and a few of them have grown beyond 15–20GB. Recently, Outlook has started lagging and showing occasional error prompts, which I suspect might be due to the oversized PST files. I am worried that if the file sizes continue to increase, they may get corrupted. Can anyone suggest the safest and most effective ways to compress or reduce the size of large PST files?
