How to Shrink a PST File Without Using MS Outlook?

I have an old PST file that has become quite large, and I want to reduce its size. The problem is that I no longer have Microsoft Outlook installed on my system. Is there any reliable method or tool to shrink or compress a PST file without Outlook? I would prefer a solution that ensures no data loss and works with large PST files. I want to make sure that no data is lost in the process. A trusted software recommendation would be really helpful.

  • If you are not using Microsoft Outlook, but you have a large PST (Personal Storage Table) file and you want to reduce its size, then you can try Softaken Compress PST Software. I have used it myself, and in this, you can compress your file without any data loss.
    Its features:
    Outlook is not required
    Can compress multiple PST files simultaneously
    Supports all Outlook versions
    The interface is quite simple, and even non-technical users can use it easily.

    If your PST file has become more than 2GB, then definitely try it once.

    This looks really helpful, especially for those who don’t want to buy or install Outlook but still need to manage PST files. I like that it’s simple enough for non-techies. Sometimes managing files feels like solving puzzles in Escape Road—you need the right tools to get out cleanly. Compressing PSTs without data loss sounds like a real lifesaver!

  • If the size of your Outlook PST file has become too large, you can try the DataVare Outlook PST Compact Expert Tool. This tool compresses the PST file without any data loss and removes unnecessary space. The best part is that you don't need to have MS Outlook installed on your system to use it. I used this tool and was able to shrink a large PST file within minutes. It has an easy interface and also supports batch compression.
