Unable to Reduce PST File Size in Outlook: Any Solution?

[THOMPSON01]

I am facing an issue with my Outlook PST file — it has become quite large, and even after deleting unwanted emails and emptying the “Deleted Items” folder, the file size has not reduced. I also tried compacting the PST file manually, but it remains almost the same size. Has anyone else experienced this issue? Is there any reliable method or tool to effectively reduce the PST file size without losing data or affecting Outlook performance?

Yes, there is a reliable solution if you’re unable to reduce PST file size in Outlook. You can use a PST Splitter tool to break a large PST file into smaller, more manageable parts. The tool divides your mailbox data by size, date, folder, or year, which helps eliminate size-related issues, improve Outlook performance, and prevent corruption. This method is especially useful when Outlook’s built-in Compact feature fails to shrink the file. By splitting the oversized PST into multiple smaller files, you can easily reopen them in Outlook without performance problems or errors. After splitting the files, use a PST File Viewer to verify the divided files and ensure their accuracy.
