How to Compress Large PST Files in Outlook 2019 Without Losing Data?

[Sofia01]

I have been using Outlook 2019 for a while, and my PST file has grown quite large, which is slowing down performance. I wanted to ask—how can I safely compress or reduce the size of a PST file in Outlook 2019?

Is there a method or reliable tool that can help reduce the size of PST files without causing data loss or corruption? Also, are there any precautions I should take before starting the compression process?

If your PST (Personal Storage Table) file in Microsoft Outlook 2019 has become too large, it can not only slow down Outlook's speed but also increase the chances of data corruption. In such a case, compressing (compacting) the PST file is a great solution. The good thing is that you can do it without losing any data.

If your Outlook PST file size has become too large and Outlook is running slow, I would recommend DataVare Outlook PST Compact Expert Software.

I have used it myself, and this tool compresses PST files in a speedy, easy, and secure way, without any data loss. The best part is that it also offers the option to save attachments in a separate folder, which further reduces the file size.

• No data loss
• All Outlook versions supported (2019, 2016, 2013...)
• Batch compression of multiple PST files

If you want to make Outlook lighter and faster, then definitely try the PST Compress tool once.
