How to Compress a Large PST File Without Losing Data?

[Sofia01]

Hi everyone,

I’m facing an issue with a large Outlook PST file that has grown over time and is causing performance issues in Outlook. I’ve archived old emails, but the file size hasn’t significantly reduced. I want to compress or reduce the size of this PST file without losing any important data or emails.

Has anyone faced a similar situation? What’s the best and safest way to compress a PST file?
Are there any built-in tools in Outlook or reliable third-party utilities that you would recommend?

Looking forward to your suggestions. Thanks in advance!

Microsoft Outlook stores emails, contacts, calendar entries, and other mailbox data in PST (Personal Storage Table) files. Over time, these files can grow significantly in size, leading to slower Outlook performance or even the risk of file corruption. One of the best ways to optimize Outlook and free up storage space is by compressing PST files without losing any valuable data.

Utilizing the Softaken Compress PST Software to simplify and smooth this solution. With the removal of extraneous data and cache space, this utility is particularly made to shrink the size of huge Outlook PST files.

Compresses large PST files without data loss

One of the key features of the Shoviv PST Compress and Compact Tool is that it preserves important data when compressing. While the software deletes duplicate items as it usually does for improved storage, it also has an option for not deleting them. You can choose to avoid deleting any duplicate items from your PST files, so nothing gets lost from your data. Additionally, the software offers you the ability to bypass the deleted items folder during processing, ensuring that no permanently deleted emails are altered. This user-defined approach offers users maximum control over their data, and the process is both safe and accurate.

Utilize the best PST compression tools when compressing large PST files. I recommend using the DataVare Outlook PST Compact Expert Solution. Since it removes unnecessary data and cache space, the application can handle compressed PST files of any size. This application allows you to compress PST files without losing any data. With this program, PST files may be compressed without any data loss. Use this program's latest trial version to give it a try for free.

Hi @Sofia01 ,


First, try Outlook’s built-in Compact Now feature (found under File > Account Settings > Data Files > Settings > Compact Now) to safely shrink the PST file without losing any emails.

If the file is still too large afterward, you can use trusted third-party tools but always back up your PST file first before using any software.
